美国的 NL 工业锂蒙脱石矿床位于加利福尼亚州的巴斯托(Barstow)附近,是一个典型的锂蒙脱石采矿和加工工业基地。在矿山人们为了控制原矿质量,需对锂蒙脱石进行选择性开采,然后进行粗碎,将1—2英时的岩石送到加工厂进行干燥和湿法分选。干燥后的锂蒙脱石在雷蒙辊式磨机中进行研磨,生产出几个级别的产品。这些产品一般是以每袋50磅或小型散装箱出售。产品中含有大约50%的锂蒙脱石,其余的成分多半是方解石。干燥过的研磨
The NL industrial hectorite deposit in the United States, near Barstow, California, is a typical hectorite mining and processing industrial base. At the mine, in order to control the quality of the ore, hematite was selectively mined and then coarsely crushed to send the 1-2-mile rocks to the processing plant for drying and wet separation. The dried hectorite is milled in a Raymond roll mill to produce several grades of product. These products are generally sold in 50-pound bags or in small crates. The product contains about 50% hectorite, the rest of the ingredients are mostly calcite. Dried ground
