现代锡的生产工艺对送往冶炼部分的原料质量提出了高的要求,随着锡精矿质量的改善,提高了锡的冶炼回收率,增加了炉子的生产能力,降低了燃料和熔剂的消耗,改善了产品的质量和减少产品的成本。在精选某些粗精矿时,锡在細泥尾矿中的損失,达到精选中全部损失的80%。精选尾矿的矿物分析表明在其中有大量的硫化物,主要是黄鉄矿、磁黄鉄矿、鉄的氧化物、褐铁矿、菱鉄矿和磁鉄矿等。
The production process of modern tin puts a high demand on the quality of the raw materials sent to the smelting part. With the improvement of the quality of the tin concentrate, the smelting recovery rate of tin is increased, the production capacity of the furnace is increased, and the consumption of fuel and flux is reduced , Improve product quality and reduce product costs. In the selection of some coarse concentrates, the loss of tin in the fine tailings, reaching 80% of all losses in the selection. Mineral analysis of selected tailings shows that there is a large amount of sulfide in them, mainly yellow ore, pyrrhotite, limonite, limonite, rhodochrosite and maggot.
