引言研究风选技术是为了从矿石和尾矿中精选粗云母,是美国矿业局推进矿物资源利用技术计划,以利保持充足矿物供应来满足国民经济和战略需要的目的之一。本文除另有说明者外,所指云母系白云母。片状云母是工业云母的两种主要形式之一。工业云母的第二种主要形式是云母屑和碎云母。这通常址指质量和大小不适于作片状云母的任何一种云母。大多数云母屑和云母碎从片岩、伟晶岩中回收,有时是精选长石和高岭土而得到的副产品。云母一般加工成适于各种目的的磨细云母。4毫米级的干磨粗云母粉用于油井钻探泥浆以克服钻探泥浆失去流通。1毫米级的云母粉可用作混凝土、石材和砖块的装饰涂层。0.75毫米级的云母粉用于制
Introduction The study of wind technology is to select coarse mica from ores and tailings. It is one of the purposes for the US Department of Mines to promote the utilization of mineral resources and to meet the national economy and strategic needs in order to maintain sufficient supply of minerals. This article refers to mica-based muscovite unless otherwise indicated. Flaky mica is one of the two major forms of industrial mica. The second major form of industrial mica is mica chips and broken mica. This usually refers to any type of mica that is not suitable for flaky mica in terms of quality and size. Most mica crumbs and micashake are recovered from schists and pegmatites, sometimes by-products from the selection of feldspar and kaolin. Mica generally processed into a suitable for various purposes, mica. Dried coarse mica powder, 4 mm, is used in well drilling fluids to overcome the loss of circulation of drilling mud. 1mm mica powder can be used as a decorative coating of concrete, stone and bricks. 0.75 mm grade mica powder is used for making
