摘要
Abstract
The CuSO4 · 5H2 O was prepared using copper residue by pressing oxidation using .The best leaching conditions were determined .The results show that under the conditions of temperature of 90℃ ,leaching time of 3 h ,excess air of 1 .6 times and the ratio between liquid volume and solid mass of 4∶1 ,the leaching of copper is greater than 99 .1% .The CuSO4 · 5H2 O prepared from the lixivium by removing Fe ,evaporation and crystallization is in line with the GB437-2009 .The leaching time shortens by 3-4 h than air oxidation method ,leaching efficiency is greatly improved .关键词
