Abstract

27,600. Vereinigte Glanzstoff - Fabriken Akt.-Ges. June 18, [Convention date]. Wet processes of recovering copper.-Copper suspended in the washing-waters obtained in the manufacture of artificial cellulose products from cuprammonia - cellulose solutions, is caused to settle by the addition of a colloid, such as starch. For example, the liquor may be that obtained by absorbing ammonia in the waters obtained by washing cellulose precipitated by alkaline reagents, and from which the ammonia has been removed by treatment with steam. The hot liquor is treated with starch made into a milk with cold water, and the treated liquor run into a number of pits, in the first of which the magma separates.
