云锡细脉带网状矿为一种少见的矿种。有用矿物呈网状嵌布在脉石中,品位很低,约为0.3％。按常规的选矿方法处理,经济上没有收益,而且该矿还有一个特点:就是中间比重(2.75—2.65)的矿石含锡最低,而大于2.75和小于2.65的含锡较高,这又给重选带来了困难。但该矿区又是该公司的主要生产矿山,而且矿体构造复杂,多层复盖,重叠交错。表层为砂矿,砂矿下部是细脉带网状矿,再下是氧化矿,硫化矿。目前表层砂矿已基本采完,而网状矿盖住了下面的氧化矿和硫化矿,若不尽快经济地利用网状
Cloud tin vein network reticular ore is a rare mineral. Useful minerals were mesh embedded in gangue, the grade is very low, about 0.3%. According to the conventional beneficiation method, there is no economic benefit. Moreover, there is another characteristic of the mine: that is, the ore with the middle specific gravity (2.75-2.65) has the lowest tin content, while the tin with the greater than 2.75 and less than 2.65 contains tin, which in turn gives heavy The election has brought difficulties. However, the mine is the company’s main production mine, and the complex ore body structure, multi-layer cover, overlapping staggered. The surface is placer, the lower part of the placer is a reticular ore belt, and then the ore and sulphide ore. At present, surface sand has been basically taken, and the reticular ore covers the following oxide ore and sulphide ore, if not quickly and economically using the reticular
