Definitions

  • amines comprised between C and C have a floating power remarkably higher than others.
  • the amount required for good flotation is about 5 times lower than that of longer chain-amines, such as C C C
  • the floating power of the following amines C C C C C remains almost constant despite any variance of the composition of the saline solution constituting the turbid liquid, whereas, in contrast it varies markedly for other longer chain-amines.
  • the diagram in FIG. 1 illustrates the variation of the flotation yield as a function of the number of carbon atoms in the amines.
  • the curves in FIG. 2 show the variation of flotation yield as a function of the consumption of the collector, for various amines.
  • the amine consumption as hydrochloride, in grams per ton of kainite ore, "and on the ordinate'is plotted the yield in percent K 0. From this diagram it is evident that the amines C C C have the highest floating power, and their consumption, other conditions being equal, is about 5 times lower than longer chain-amines (C C C C
  • the diagram in FIG. 3 shows, as an alternative, the influence of the composition of saline solution upon the floating power of the amines.
  • the Mg contents in grams per liter of the solutions indi- 3,059,773 Patented Oct. 23., 1962 cated in the table in column 1, and on the ordinate the yields in percent K 0.
  • FIGS. 1, 2, 3 and the following of an illustrative character presented without intent to limit the present invention, show synthetically the results obtained by the tests.
  • the amine consumption of gr./ton relates to the use of freshly prepared saline solutions. In industrial practice, such consumption is greatly reduced by recycling the solutions which contain amine dissolved therein.
  • EXAMPLE 1 Kainite mineral 1000 gr. Type C solution 1500 cc. n-Primary decylamine (in form of hydrochloride) 80 gr./ton. Cyclohexanol 80 gr./ton. Balance:
  • EXAMPLE 8 Type C solution 1500 cc. Mixture of amines constituted of 30% n-nonyl, 35% n-decyl, 35% n-undecyl 80 gr./ ton. as hydrochloride. The rest according to Example 1.
  • the analyses were carried out using filtered and dried products.
  • the overweight of the products with reference to the weight of the starting mineral is due to the salts from the saline imbibing solution.
