一、矿石特性该矿床矿石风化极为严重,原矿中约含有45%小于0.075公厘的矿泥,含铜0.78%,97%以上为氧化铜,而结合氧化铜占总量的81%。矿石的物相分析结果列如表1。矿石中含铜矿物主要是孔雀石,此外尚有少量斑铜矿及微量的黄铜矿。孔雀石呈不规则的碎屑状产出;部分则呈不规则粒状嵌布于石英矿块表面及褐铁矿中;也有少部分呈粒状集聚体产出。粒度由0.04～
First, the ore characteristics The ore weathered extremely serious ore, ore contains about 45% less than 0.075 mm of sludge, containing 0.78% copper, 97% more than copper oxide, copper oxide and copper combined accounted for 81% of the total. The phase analysis results of the ore are listed in Table 1. Copper ore minerals are mainly malachite, in addition there is a small amount of berylite and trace chalcopyrite. Malachite was irregular crumb-shaped output; part was irregularly granular embedded in the surface of quartz ore and limonite; also a small part of the granular aggregates were produced. Particle size from 0.04 ~
