crushing of clay for alum production

Production Of Liquid Alum Coagulant From Local Saudi Clays

Several processes have been suggested for producing aluminum sulfate from clay. Most of the reported processes include calcination of clay before extracting alumina by treatment with sulfuric acid. In most reported literature, the effect of clay grinding before calcination was not paid enough attention.

11.25 Clay Processing

consolidation of clay, mud, or silt. Common clay and shale are composed mainly of illite or chlorite, but also may contain kaolin and montmorillonite. Most domestic clay is mined by open-pit methods using various types of equipment, including draglines, power shovels, front-end loaders, backhoes, scraper-loaders, and shale planers. In addition,

5 Aggregate Production - IN.gov

CRUSHING The first step of processing begins after the extraction from quarry or pit. Many of these steps also are common to recycled materials, clay, and other manufactured aggregates. The first stag e in most operations is the reduction and sizing by crushing. Some operations, however, provide a step prior to crushing called scalping.
