Investigations have been carried out to evolve a grinding aid useful in grinding a 40% iron-bearing magnetite containing quartz as the major gangue, based on studies conducted with pure magnetite, pure quartz and its synthetic mixture. These investigations established that an addition of 200 g of CaO per metric ton of ore was the most

  • Mineral Additive in the Production of New Cement Types

    2020-4-28 · The conducted studies have shown that low grade nephrite can be used as mineral additives in cement production. This will allow development of not only a new type of product, but also reduction of the negative impact of cement production on the environment. Keywords: nephrite deposits; low-grade nephrite; mineral additive; cement 1. IntroductionMinerals Free Full-Text Nephrite-Bearing Mining ,The low grade nephrite can act here as mineral additives. In the course of the research, the optimal amount of low grade nephrite waste additive was determined, which is 30% of the cement mass. The grinding time of a raw mix is 10 min. It was found that introduction of the additive affects the hydration activity of cement compositions.

Alince (1979) carried out a variety of studies, all pointing to advantages of using positively charged filler materials.

  • The chemistry of silica and its potential health benefits

    When associated with metals or minerals the family of silicates is formed. There are several water soluble forms of silica referred collectively to as silicic acid (ortho, meta, di, and tri-silicates), which are present in surface and well water in the range of 1--100 mg/L. Orthosilicic acid is the form predominantly absorbed by humans and isSafety and efficacy of bentonite as a feed additive for,2017-12-18 · Amendment: An editorial correction was carried out that does not materially affect the contents or outcome of this scientific output.
