why to brighten feldspar?

1.       What is Feldspar used for? Orthoclase and Albite are more used for industrial process. In 2011,  20.7 million Tones of feldspar were produced, mostly by three countries: Turkey (5 Mt), Italy (4.7 Mt) and China (2.1 Mt)(USGS). Feldspar is a common raw material used in glassmaking, ceramics, and to some extent as a filler and extender in paint, plastics, and rubber. Feldspar is ground to about 20 mesh for glassmaking and to 200 mesh or finer for most ceramic and filler applications. ...

About Feldspar I

1.      What is Feldspar? The feldspars (KAlSi3O8 – NaAlSi3O8 – CaAl2Si2O8 – BaAl2Si2O8) are a group of frame-like structure anhydrous aluminosilicate minerals, which are the most common mineral in the Earth, making up as much as 60% of the Earth's crust. Generally speaking, there are three categories of feldspar: orthoclase (K-feldspar), plagioclase and celsian. Feldspar has two directions of cleavage that meet at close to a 90 degree angle. The included angle between two sets of cleavages of orthoclase is equal to...

On Recovery and Process of Red Mud/Red Sludge II

2. Iron Recovery from High-Fe Red Mud Research on the technology of recovery iron from red mud was started early in 1970s. Iron can be separated and enriched through reducing roasting and a series complex processing. While the means of wet high gradient magnetic separating red mud output directly from Bayer process is a simple and feasible way. In October of 2010, Aluminum Corporation of China (CHINALCO) announced their dramatic breakthrough on iron recovery from red mud. Guangxi Branch of CHINALCO separates iron by high gradient magnetic...

On Recovery and Process of Red Mud/Red Sludge I

1. What is Red Mud? Red mud (bauxite tailings, bauxite residues) is a solid waste product of the Bayer process to provide alumina. About 1-3 tones of red mud is generated for each tones of alumina, the ratio depends on bauxite ores. Red mud reservoirs...
