METHOD OF MANUFACTURING A SEPARATION FENCE AND SEPARATION FENCE
FIELD OF THE INVENTION
The present invention relates to a method of manufac¬ turing a separation fence to be used in a hydrometal- lurgical liquid-liquid solvent extraction settler. Further, the invention relates to a separation fence. BACKGROUND OF THE INVENTION
Separation fences are used in a hydrometallurgical liquid-liquid solvent extraction settler to enhance coalescence of the dispersion. In the VSF® technology (stands for Vertical Smooth Flow) developed by the ap- plicant the separation fences are so-called DDG® fenc¬ es (Dispersion Depletor Gate) (disclosed e.g. in docu¬ ment US 7,517,461) .
In prior art, the separation fence is typically manu- factured of a fibre-reinforced plastic composite (FRP) by hand laminating. The fence fabricated by hand lami¬ nation has many disadvantages. Hand lamination makes the surfaces of the fence, which are in contact with the liquid flow, rough and the edges sharp so that vortices and dead areas are created in the flow. Sharp edges cause unwanted eddies, spouts and jets. This causes scale build-up on flow patterns and the fence is trapping crud. The cleaning of the fence is time- consuming and cumbersome. The liquid flow on the rough surfaces and sharp edges of the fence also causes electrostatic charging which may cause igniting of the flammable atmosphere in the settler. Ignition of the volatile organic compounds (VOC) , which are released from the hydrocarbon based solvents, can occur if suf- ficient electrostatic energy is released in a static discharge. As a manufacturing method of the fence, hand lamination is slow, costly and vulnerable to poor craftsmanship. In hand lamination, also air bubbles may easily remain inside the structure, weakening the fence structure.
OBJECT OF THE INVENTION
The object of the invention is to eliminate the disad¬ vantages mentioned above. In particular, it is an object of the present inven¬ tion to provide a method of manufacturing a separation fence and a fence which enable a remarkable reduction in fabrication costs of the fence. It is also an object of the present invention to pro¬ vide a method of manufacturing a separation fence and a fence which enable minimizing the local production of unwanted vortices, eddies, dead areas, spouts and jets in the flow when it contacts the surfaces of the fence.
It is also an object of the present invention to pro¬ vide a method of manufacturing a separation fence and a separation fence which enable minimizing the scale build-up and trapping of crud in the fence, thus also minimizing the time needed for maintenance.
It is also an object of the present invention to pro¬ vide a method of manufacturing a separation fence and a fence which enable minimizing the VOC emissions and electrostatic charging of the solvents, thus prevent¬ ing fires in the solvent extraction plant.
SUMMARY OF THE INVENTION
According to a first aspect, the present invention provides a method for fabricating a separation fence to be used in a hydrometallurgical liquid-liquid sol¬ vent extraction settler. In the method, the fence is manufactured of a polymer resin material. In accord¬ ance with the invention the fence is manufactured as a shell-like integral piece by rotational moulding.
According to a second aspect, the present invention provides a separation fence to be used in a hydromet¬ allurgical liquid-liquid solvent extraction settler, which fence is made of a polymer resin material. In accordance with the invention the fence is a rotation- ally moulded shell-like integral piece.
Rotational moulding is an established mass-production method which is much more economical than hand lamina¬ tion. In rotational moulding the manufacturing is performed in a mould. The surfaces of the mould can be made very smooth and all the edges can be rounded so that the fence gets similar characteristics. There- fore, the smooth surface and rounded edges contacting the solvent flow minimize local production of vorti¬ ces, eddies, dead areas, spouts and jets in the flow when it contacts the surfaces of the fence. Scale build-up and crud trapped in the fence are minimized, as well as the time needed for maintenance. VOC emis¬ sions and electrostatic charging of the solvents are minimized, thus minimizing the risk for fires in the solvent extraction plant. In one embodiment of the method, the method comprises: fabricating a mould composed of two mould halves, com¬ prising a first mould half and second mould half, said mould halves having walls, the inner surface of which corresponds to the outline of the fence; supporting the mould to be rotational about two perpendicular ax¬ es; pouring a charge of a polymer resin material powder inside the first mould half; installing the second mould half on the first mould half to close the mould; rotating the mould around the two perpendicular axes; heating the mould while it is rotating around the two perpendicular axes to melt the polymer resin material and to disperse and stick it to the wall of the mould as a layer having a substantially even thickness and forming the fence; stopping the heating of the mould; cooling the mould; opening the mould by separating the mould halves and removing the fence from the mould; and, if needed, performing finishing operations for the fence .
In one embodiment of the fence, the fence has a gen¬ eral shape of a flat rectangular casing having a hol- low inner space.
In one embodiment of the fence, the fence comprises a vertical front wall, a vertical rear wall, two verti¬ cal side walls, a top wall and a bottom wall. "Front" and "rear" relate to the orientation of the fence when it is installed in the settler in relation to the di¬ rection of flow of solvents. The front wall is the wall facing the flow and the rear wall is the trailing wall .
In one embodiment of the fence, the front wall com¬ prises an inlet opening located at the lower part of the front wall, said inlet opening being, in opera¬ tion, adapted to receive a flow of dispersion to enter the inner space between the front wall and the rear wall, and an outlet opening located at the rear wall at an elevated level in relation to the inlet opening so that, in operation, the dispersion is forced to flow vertically in the inner space between the front wall and the rear wall and out trough said outlet opening . In one embodiment of the fence, the fence comprises through-channels extending through the fence at the upper part of the fence at a level above the outlet opening .
In one embodiment of the fence, at least one of the front wall and the rear wall comprises outwardly di¬ rected bulges extending horizontally along the width of the fence, the bulges thus forming complementary recesses at the inner surfaces of the fence facing the inner space.
In one embodiment of the fence, the polymer resin ma¬ terial comprises carbon fibers. The addition of carbon fibers reinforces the structure and reduces the static electrical charging.

In the method for fabricating a separation fence 1 to be used in a hydrometallurgical liquid-liquid solvent extraction settler, the fence 1 is manufactured as a shell-like integral piece by rotational moulding.
A mould 2 composed of two mould halves 21, 22 compris- ing a first mould half 21 and second mould half 22 is manufactured. The mould halves 21, 22 have walls, the inner surface of which corresponds to the outline of the fence 1. Preferably, the mould halves 21, 22 are made of sheet metal, and thus they have a thin metal wall with a good thermal conductivity.
As shown in Figure 1, the mould 2 is supported in a rotation moulding machine so that the mould is rota¬ tional about two perpendicular axes. A charge of a polymer resin material powder 3 is poured inside the first mould half 21. The polymer resin material powder 3 may include suitable additives, such as carbon fi¬ bers . As shown in Figure 1, the second mould half 22 is in¬ stalled on the first mould half 21 to close the mould 2.
As shown in Figure 3, the mould 2 is placed into an oven wherein the mould 2 is heated while it is rotat¬ ing around the two perpendicular axes. The heat melts the polymer resin material. Due to the rotational movement, the melted polymer resin material disperses and sticks to the wall of the mould 2 as a layer hav- ing a substantially even thickness and forming the fence 1. As shown in Figure 4, after heating, the mould 2 is placed into a cooling station wherein the mould 2 is cooled by spraying a cooling fluid. As shown in Figure 5, after cooling, the mould 2 is opened by separating the mould halves 21, 22 from each other. The fence 1 is removed from the mould.
If needed, finally, finishing operations, such as ma- chining, may be performed on the fence 1.
Figures 6 to 8 show a separation fence 1 to be used in a hydrometallurgical liquid-liquid solvent extraction settler, which fence is made of a polymer resin mate- rial.
The fence 1 is a rotationally moulded shell-like inte¬ gral piece that has a general shape of a flat rectan¬ gular casing having a hollow inner space 4. The fence 1 comprises a vertical front wall 5, a vertical rear wall 6, two vertical side walls 7, 8, a top wall 9 and a bottom wall 10.
The front wall 5 comprises an inlet opening 11. The inlet opening 11 is located at the lower part of the front wall 5. In operation, the inlet opening 11 re¬ ceives the flow of the dispersion which enters the in¬ ner space 4 between the front wall 5 and the rear wall 6 and is forced to flow upwards to an outlet opening 12 which is located at the rear wall 6 at an elevated level in relation to the inlet opening 11. In operation, the dispersion is discharged from the inner space trough said outlet opening 12. At the upper part of the fence 1, at a level above the outlet opening 12, the fence 1 comprises through- channels 13 extending through the fence. The front wall 5 and the rear wall 6 both comprise outwardly directed bulges 14 extending horizontally along the width of the fence 1. The bulges 14 form complementary recesses 15 at the inner surfaces of the fence facing the inner space 4. In operation, these recesses 15 enhance coalescence of the dispersion.
It is obvious to a person skilled in the art that with the advancement of technology, the basic idea of the invention may be implemented in various ways. The in¬ vention and its embodiments are thus not limited to the examples described above; instead, they may vary within the scope of the claims.
