据JOM报道,酸压氧化法通常被认为是难处理的含金硫化矿石和精矿的最有效预处理法,尽管对有些矿石是无效的。但对于常含有碳质物料和硫化物的矿石和精矿,焙烧仍然是氰化之前的最有效预处理法。然而,SO_2和As_2O_3的析出可能引起环境的严重损害,使得焙烧变成一个没有 According to JOM, acid-pressure oxidation is generally considered to be the most effective pretreatment method for refractory gold-bearing ores and concentrates, although not effective for some ores. However, for ores and concentrates that often contain carbonaceous materials and sulphides, roasting remains the most effective pretreatment prior to cyanidation. However, the precipitation of SO 2 and As 2 O 3 may cause serious environmental damage, making the roasting into one without
