동(銅), 연(鉛), 아연광물(亞鉛鑛物)의 회수(回收)에 관(關)한 기초적(基礎的) 연구(硏究)

The conclutions arrived at as a result of experimental work are as follow; 1. The use of kerosene as a collector was found essential to produce a good recovery of chalcopyrite, galena and zincblende under the condition of high pH(below 2). 2. Temperature doesn't seemingly effect the flotation of chalcopyrite, galena and zincblende. 3. The minimum concentration of kerosene as a collecter was 26mg kerosene per liter of solution.
