南桐煤矿洗选厂在79年建立了硫精砂车间,从洗矸废弃物中回收硫精砂。在设计时,必须对矿区4、5、6、三煤层中硫精砂赋存情况了解,为此摸索出配制高密度溶液以及洗矸浮沉试验的方法,以为硫精砂工业性试验提供有意义的技术资料。因为洗矸的密度一般大于2,硫精砂密度也都在2以上。当时由于尚无高密度溶液,因此采用三溴甲烷和四氯化碳。兹介绍高密度溶液的配制及浮沉试验。一、高密度溶液的配制根据下式计算两有机溶剂之量: S_1x+S_2y=100×2.3 x+y=100
Nantong coal washing plant in 79 established sulfur fine sand workshop, from the refuse and waste recycling sulfur concentrate. In the design, it is necessary to understand the occurrence of sulfur fine sand in the coal seams 4, 5, 6, and 3 in the mining area. Therefore, the method of formulating high-density solution and laundering rock wash test should be worked out to provide meaningful significance for industrial testing of sulfur concentrate Technical information. Because the density of the gangue is generally greater than 2, sulfur sand density are also above 2. Tribromomethane and carbon tetrachloride were used at that time because no high-density solution was available. Here to introduce the preparation of high-density solution and floating test. First, the preparation of high-density solution Calculate the amount of two organic solvents according to the following formula: S_1x + S_2y = 100 × 2.3 x + y = 100
