近年来,许多生产、科研单位对煤矸石回收硫进行了大量的实验研究工作,有的洗煤厂根据试验结果建成了回收硫铁矿车间,投产后取得了明显的经济效益。试验及生产实践都表明,采用重选法回收煤矸石中的硫铁矿是有效的、经济的。本文对韩桥煤矿矸石选硫工艺试验作一简介。一.煤矸石的物理化学性质 1.主要的矿物组成:煤矸石中除少量的煤炭外,主要的矿物有石英、方解石、黄铁
In recent years, many production and research institutes have carried out a large amount of experimental research on sulfur recovery from coal gangue. Some coal washing plants have completed the recovery of pyrite plant according to the test results and have obtained obvious economic benefits after putting into production. Tests and production practices have shown that the use of re-election method of coal gangue pyrite recovery is effective and economical. This article gives a brief introduction of the coal gangue sulfur extraction process test in Hanqiao coal mine. I. Physical and chemical properties of coal gangue 1. The main mineral composition: coal gangue in addition to a small amount of coal, the main minerals are quartz, calcite, pyrite
