Definitions
- the quantity of acid proportional to the raw material consumed is substantially constant where the resulting bleaching power of the product is equivalent.
- the raw earth is diluted, either, as formerly with water by adding simultaneously or subsequently thereto, one or-several of th'esalts mentioned or by adding one of the. waste iiquors 55 mentioned, or, by employing a corresponding mixture respectively.
- the preparation proper of the aqueous muddy suspension is already effected with the salt solutions or wasteliquors, in order to avoid the unnecessary dilution through the depositing water.
- the quantity of acid added depends upon the kind and quantity of salt solutions or waste-liquors used. Naturally the saving in acid is entirely dependent upon the kind of raw clay, and the quantity and quality of the salt solutions or waste-liquors used. Even in the most unfavorable instance it is still possible to get along with considerably smaller quantities of fresh acid than such was necessary according to the former method, for obtaining an equally effective bleaching power.
- .moist state as it comes from the pit containing ll40kilograms of dry substance, are reduced to mud with-1420 litres of water, whereupon the '.-material is mixed with 1260 litres of hydrochloric acid oi. 18 Be. 36 kilograms of, hydrochloric acid per 100 kilograms of drysubstance), then boiled and further. treated in known manner.
- the output amounts to-"7-8.5 per cent of the dry substance used.
- the output is 82 per cent of the dry substance employed, having an equally effective bleaching power as the bleaching clay obtained according to Example 1.
- the output likewise amounts to 82 per cent of the dry substance employed, having an equally effective bleaching power as the bleaching-clay obtained according to Example 1.
- Process of activating bleaching clay material comprising suspending the clay material in an aqueous solution of a salt, adding to the suspension a quantity of free acid oi said salt, and boiling the acidified suspension until the acid is completely used, whereby the acid treatment is effected entirely in the presence of salts of said v acid.
- Process of activating bleaching clay material comprising suspending the clay material in an aqueous solution of a sulfate, adding to the suspension a quantity of sulfuric acid, and boiling the acidified suspension until the acid is completely used, whereby the acid treatment is etfected entirely in the presence of salts of said acid.
- aqueous salt solution is the liquor from a previous acid treatment of the clay material.
