method of concentration of copper ore

a statistical approach to the experimental design of the sulfuric acid

by using the plackett burman method it was possible to select the variables that had the largest influence on the percentage of copper extracted at the sulfuric acid leaching stage these were temperature of leach solution stirring speed concentration of sulfuric acid in the leach solution and particle size of the ore
