  • Method for processing wastes resulting from production of phosphorus, namely, slime and off-gasses, with utilization of the resultant products
    Patent number: 4478633
    Abstract: The method comprises processing slime and off-gases resulting from the production of phosphorus with an aqueous solution of copper sulphate having a concentration of from 15 to 50% at a temperature within the range of from 20.degree. to 80.degree. C. As a result, two products are obtained, i.e. a liquid product and a solid one.The solid product containing mainly copper phosphide as well as fluorides and chlorides of alkali metals and silicon, and silicates of calcium and aluminium, is used as a modifying and refining agent for hypereutectic silumines and for the manufacture of a copper-phosphorus alloy.The liquid product containing phosphoric acid, sulphuric acid and copper sulphate is used as starting product for the preparation of a copper-containing fertilizer.The method according to the present invention makes it possible to modify the production of phosphorus so as to eliminate the formation of secondary wastes and improve the evnironmental control.
