The SiO(OH) 3 − hydrolyzed by sodium silicate adsorbs on the surface of muscovite, which leads to the dispersion of muscovite pulp, and thus improves the grinding effect. This study has some reference significance for improving the production efficiency of muscovite powder and the application of grinding aids.

Herein, hydrogels based on starch from corn, sweet cassava and bitter cassava were prepared by a straightforward approach. The hydrogels were obtained by an oxidation process using the redox system KMnO 4 /NaHSO 3 which leads to the formation of carbonyl and carboxyl groups with minimum polymer hydrolysis. The resulting oxidized samples as well as the native starches were extensively ...

Mineral Processing. Mineral processing is the process in which chemical or physical methods are used to separate the useful minerals in the ore from the useless minerals (usually called gangue) or hazardous minerals, or to separate multiple useful minerals. In the early years, mineral processing was called mineral concentration or mineral ...

Generally, application of the hydrolyzed starch increases the capacity and throughput of mineral ores during the grinding stage in mining processes, particularly in recovery of mineral fines from ore. This will benefit operations by decreasing downtime and moving more ore through the comminution process in shorter time periods.

Grinding is the most energyintensive step in mineral beneficiation processes. The use of grinding aids (GAs) could be an innovative solution to reduce the high energy consumption associated with size reduction. Surprisingly, little is known about the effects of GAs on downstream mineral beneficiation processes, such as flotation separation.

The use of grinding aids in the cement industry to improve the grindability and product throughput of the cement clinker dates to 1930 . Most grinding aids are organic liquids, such as triethanol amine, glycerol, alcohols, propylene glycol, organosilicones, diethylene glycol, and resins, etc. [27,81].

In this paper, different doses of sodium hexametaphosphate (SHMP) were added as grinding aids in the process of muscovite grinding, and the effect of SHMP on the grinding efficiency of muscovite was studied. The grinding experiment results show that the grinding efficiency increases significantly with the increase in SHMP dosage. The mechanism of SHMP improving the grinding efficiency of ...

The general use of chemical grinding aids involving several different mechanisms for increasing throughput in the wet grinding of ores has been discussed in a number of recent publications. It appears from industrial scale testing that the use of selective dispersants with certain prespecified operating conditions is an approach which can produce two important results: first, increased feed ...

Acid Hydrolysis of Starch. Mineral acids like sulphuric or hydrochloric acids are used in treating starch to obtain acidhydrolyzed starch. This process of acidhydrolysis of starch results in the depolymerization of the starch polymer (De siqueira et al., 2017).Acidhydrolysis of starch is performed to remove fatty substances from native starch and improve the starch's physical and ...

Grinding is an indispensable step in mineral processing to reduce particles' size and liberate minerals before they are subjected to further separation processes. Grinding is characterized by high energy consumption and low energy efficiency (~ 1%) (Cheng et al. 2019; Liu et al. 1989; NapierMunn 2015).
