THE PRODUCTION TECHNIQUE OF BENTONITE PROCESSING

Aug 20, 2013· INTRODUCTION OF BENTONITE: Bentonite is a kind of clay, often containing a small amount of illite, kaolinite, chlorite, Elo stone, quartz, feldspar, zeolite and calcite, which hardness is 1 ~ 2 and density is of 2 ~ 3g/cm3. According to the kinds of exchangeable cation, content and layer charge, bentonite can be divided into Na

US3865240A Purification of bentonite Google Patents

Finely comminuted, crude bentonite may be purified of accompanying quartz, muscovite, illite, feldspar, iron oxide and like impurities by pouring an aqueous slurry of the clay into a very dilute aqueous solution of a technical grade of sodium hexametaphosphate, and letting the mixture stand a few minutes, whereby almost the entire mineral impurities present are precipitated.

Mining and processing Bentonite

Mining and processing. Bentonite is a raw material present in many countries and mined in open pit quarries. Bentonite deposits are most often quite large, with lenticular beds, only a few meters deep. Bentonite production process features ore mining, sodium activation if required -, drying, and milling.

How to Use Bentonite to Clarify Wine Winemaker's Academy

Bentonite is a unique clarifier in that it is the only one that may be used during fermentation as well as afterward. When you add bentonite at the beginning of fermentation you’re relying on the carbon dioxide bubbles that form to carry the bentonite up through the wine and, when the bubble pops, let it fall back down to the bottom.

What is Bentonite? Industrial Minerals Association

Oils/Food Markets: Bentonite is utilized in the removal of impurities in oils where its adsorptive properties are crucial in the processing of edible oils and fats (Soya/palm/canola oil). In drinks such as beer, wine and mineral water, and in products like sugar or honey, bentonite is used as a clarification agent.

Mechanisms of Advanced Oxidation Processing on

advanced oxidation (AO) process is employed in a green sand system, the foundry needs 20-35% less makeup bentonite clay than when AO is not employed. We herein sought to explore the mechanism of this enhancement and found that AO water displaced the carbon coating of pyrolyzed carbonaceous condensates that otherwise accumulated on the bentonite

Review Comparison of bentonite and zeolite Article as

Bentonite content of 2.5% has a higher effectiveness than 5% bentonite content in patchouli oil purification [13]. On the addition of 2,5%, bentonite PA content on patchouli oil reached 31% whereas if patchouli oil is added bentonite with 2.5%, PA levels only 29%. This means that bentonite is more economical when used as an adsorbent.
