一、前言石茶次生矿床属高硅铁质难选的深度氧化铜矿。原矿平均含铜2.5％左右,结合铜含量5～40％,含泥量很高,-0.07毫米占48％以上,平均含水27.1％,是国內少有的氧化铜矿床。对石某铜矿次生矿,1964年以来进行了直接浮选、浸出—置換—浮选、离析—浮选……等八个处理方案的试验研究,结果表明,离析 First, the foreword The secondary tea deposits are high-grade ferrosilicon refractory depth of copper oxide. Ore average copper content of about 2.5%, with copper content of 5 to 40%, mud content is high, -0.07 mm accounted for more than 48%, an average of 27.1% moisture, is a rare copper oxide deposits. For Shimou copper mine secondary ore, since 1964, direct flotation, leaching - displacement - flotation, segregation - flotation ... ... and other eight treatment programs of the pilot study showed that the segregation
