在自然界中,純淨含有一种金属矿物的矿石是很少的。因此,选矿作业应該看作是二种或二种以上矿物互相分离的过程。不过在多金属矿石的选矿作业里,分选作业技术条件的控制就更复杂和重要了。本文拟就多金屬矿石浮选过程中的有关問題作一些探討。 礦石的物質組成与嵌鑲特性問題 矿石的物質組成、矿物的結構关系、嵌鑲情况、矿物间的共生关系等方面都直接影响到选矿方法的选擇与浮选結果。首先在矿石中的各种矿物含量比,就能够直接影响到各种矿物的浮选結果,这是目前浮选效果所限制
In nature, there are very few pure minerals that contain a metallic mineral. Therefore, dressing operations should be seen as two or more than two minerals separated from each other’s process. However, in the polymetallic ore beneficiation operations, the control of sorting operation technical conditions is more complex and important. This article intends to make some discussions on the related issues in the flotation process of polymetallic ores. Ore composition and mosaic characteristics of mineral matter composition, mineral structure, mosaic conditions, symbiotic relationship between minerals and other aspects have a direct impact on the beneficiation method selection and flotation results. First of all minerals in the ore than the ratio can directly affect the flotation results of various minerals, which is limited by the current flotation effect
