用 H_2SO_4溶浸含1.13%或1.6%铜及0.02%钼的氧化矿。初步实验室试验用 H_2SO_4200克/升,萃取了铜88.7—92.7%,在0.47%硫化物的情况下酸用量为3.7公斤/公斤铜相对比在硫化物3.0%的情况下酸用量为6.9公斤/公斤铜。用 H_2SO_410—50克/升作了≤11周的堆浸试验。萃取了28.7—54.4%Cu。Mo 的回收率低。用 HCl 或含水氯化物溶液不如 H_2SO_4有效。存在有 CaO 及硫化物则降低浸出效果。
Oxygenated ore containing 1.13% or 1.6% copper and 0.02% molybdenum was impregnated with H 2 SO 4. Preliminary laboratory tests using H 2 SO 4 - 4200 g / L, extraction of copper 88.7-92.7%, 0.47% sulfide in the case of acid consumption of 3.7 kg / kg of copper relative to the case of sulfide 3.0% acid dosage of 6.9 kg / Kg of copper A heap leaching test of ≤11 weeks was made with H_2SO_410-50 g / L. Extracted 28.7-54.4% Cu. Mo recovery rate is low. With HCl or aqueous chloride solution as H_2SO_4 effective. The presence of CaO and sulphide reduces the leaching effect.
