Abstract
1,256,556. Shock impregnation mining of minerals. HENKEL & CIE G.m.b.H. 30 Sept., 1969 [1 Oct., 1968], No. 47913/69. Heading E1F. [Also in Division C3] In a shock impregnation process the impregnating solution is an aqueous solution having a content of from 0.1-5% by weight of galactomannans, and from 2 to 50% by weight, based on the amount of galactomannans, of borate, the solution having a pH of 5 to 10'. The borate is suitably a mixture of borax and boric acid but the borax may be mixed with other substances, such as sodium bisulphate or hydrochloric acid.
