what is mica minig Mining-pedia

There are some common mica underground mining methods: shrinkage method, filling method and room and pillar method. The entire underground mining is carried out in layers from bottom to top, with a height of 1.8-2 meters. After blasting, the falling ore will fall onto the previously mined filling layer.

5 Methods of Mica Separation Mining-pedia

Flotation is mainly used to separate fragmental mica. There are currently two flotation methods. The first method is to flotation mica in acidic medium with amine collector, the pH value is controlled below 3.5, and the upper limit of the flotation particle size is 1.2mm. And des is required before flotation.

Mica Mineral Flotation ArrMaz

Mica ores are usually found in pegmatites associated with quartz, feldspar, tourmaline, apatite, spodumene, beryl, kaolinite and limonite minerals. Scrap and flake mica used to produce ground mica are usually recovered using crushing, screening and gravity methods, and when flotation is used, the mica ore must be deslimed typically at 100 mesh.
