Mining & Processing. Bentonite is surface mined through a process called back-casting where reclamation is performed by filling the mining pits with soils from subsequent pits while the mine is in production. Typically the topsoil layer is about 30 inches deep, which is removed using heavy equipment.

paragraphs describe the steps used to process each of the six categories of clay. Table 11.25-1 summarizes these processes by clay type. Kaolin
Once these elements are obtained, the physical mining process—or, the first step of production—begins. The mining process can be broken down into two categories: Surface Mining. Workers begin by striping the overburden, which is rock, soil, and ecosystem that lies above the surface.

Bismuth. Bismuth (Bi) is a silvery-white metallic element with a pinkish tint on freshly-broken surfaces. The most common bismuth minerals are bismuthinite and bismite, but most bismuth is recovered as a by-product from lead processing. Most bismuth is produced from mines in China, Mexico and Bolivia. Only one mine in Bolivia is a primary

Bentonite is used as a binder for proper balling of the filter cake particles in to spherical shaped balls with certain compression strength. The bentonite is stored and ground in a Vertical mill by dry grinding process to desired fineness (−200 mesh, 80%). The powdered bentonite is stored for further mixing process.

Deposits of Bentonite are mostly exploited by mining. Having an approximately 30% content of moisture, still, the extracted bentonite is noticeably solid. Initially, the material is sliced or crushed and activated by adding Na2CO3 (soda ash), if required. Afterward, Bentonite is dried, using forced drying or the air, to touch the required moisture.

Bentonite is an effective, widely used binder in the iron ore pelletizing process. Its low price is an important factor for its extensive use. However, bentonite incorporates silica and alumina, which are undesirable contaminants to pellets. Additionally, it is a natural material with variable composition depending on its origin.
