A_3是由水玻璃与草酸按一定比例配成的一种混合抑制剂,它能有效地抑制碳质页岩和含白云石的脉石,将A_3用于内蒙古东升庙多金属硫铁矿锌硫样的浮选,抑制碳质和白云石脉石,效果显著。 1 矿石性质东升庙多金属硫铁矿为特大型多金属沉积变质型硫铁矿矿床,主要分为单硫和锌硫两大工业类型。锌硫矿石中主要有用矿物有:磁黄铁矿、黄铁矿、铁闪锌矿及少量方铅矿和黄铜矿,矿石中伴生银、钴、镉等贵金属,主要脉石矿物有白云石、方解石、石英、石墨和长石等。锌硫样中铅锌矿物多呈胶结镶嵌状的包裹体或港湾状,锌以铁闪锌矿形式存在,且矿物中存在少量
A_3 is a mixture of water glass and oxalic acid formulated as a mixed inhibitor, which can effectively inhibit the carbonaceous shale and dolomite gangue, the A_3 for Dongshengmiao polymetallic pyrite in Inner Mongolia zinc and sulfur Like the flotation, inhibition of carbonaceous and dolomite gangue, the effect is remarkable. 1 ore properties Dongshengmiao polymetallic pyrite is a super-large polymetallic sedimentary metamorphic pyrite deposit, which is mainly divided into two types of single-sulfur and zinc-sulfur industries. The main useful minerals in zinc and sulfur ore are: pyrrhotite, pyrite, marmatite and a small amount of galena and chalcopyrite, accompanied by silver, cobalt, cadmium and other precious metals in ore, the main gangue minerals are dolomite , Calcite, quartz, graphite and feldspar. Zinc and sulfur in the lead and zinc minerals mostly inlaid cement-like inclusions or bay-like, zinc in the form of marbling, and the presence of minerals in small amounts
