Abstract
The paper discusses a new method for producing cupric feed copper sulfate by hydyometallurgy,based on black and red copper ores.The optimized condition by orthogonal design is determined as follows:copper:ammoninm bicarbonate:ammonia=1∶1.1∶1.3(molar),forrign matter:purifying agent=1∶2(mass ratio),The reaction time is 3 hr,and production ratio is 96%,the quality is up to GB8249-87 standard of feed grade.
