This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.

Flotation is one of the commonly used methods for silica sand beneficiation. It is mainly used to remove mica and feldspar minerals that are symbiotic with silica sand. However, in the actual production process, the flotation process will be affected by many factors, including: feed size, slurry temperature, slurry liquid chemical composition, flotation reagents and other …

Applying aliphatic amines and petroleum sulfonate mixing collector in strong acidic environment using H 2 SO 4 or HCl as pH regulator, selective flotation separation of feldspar from quartz [11,12,13] could be achieved. However, the effectiveness of this separation method is worse than conventional fluorine-containing flotation.

With its balance between cost and material performance, Silicon is one of many choices for MEMs, power electronics, and biosensors, each with their own industry needs.

Generally, reverse flotation is used under acidic or alkaline conditions, but a majority of processing plants mostly use amine cationic collectors for reverse flotation under acidic conditions. (2) When separating potash feldspar and quartz, acid flotation, neutral flotation, and alkaline flotation can be used. a) The acid flotation: under the ...

In another study, the effect of grinding aids on the amount of clinker usage and the amount of grinding energy consumed during grinding was investigated [14] . Amines, glycols, and acids were used in this study as grinding aids. The glycolic grinding aid used was a mixture of diethylene glycol (DEG) and propylene glycol (PG).

Ryncarz and Laskowski correlated the observed effects to the zeta potential values of quartz in amine solutions where grinding efficiency was low at pH conditions close to the point of zero charge (PZC) values. Halasyamani et al. investigated the effect of pH on the grinding of quartz and calcite with HCl and NaOH in a ball mill. The maximum ...

Amine was found to improve grinding, pulp fluidity, and primary breakage of quartz suspensions, especially in the alkaline pH range. These beneficial effects are attributed to the formation of highly surface-active amineaminium complexes in this pH range.

Grinding of quartz in amine IOlu- tiona. Int. J. Miner. PrOCell., 6: 105-117. This study, initiated to investigate the effect of additions of surface active fealents on the wet-lrindinl of ores, hu shown that improved grinding can be obtained at certain levels of amine concentration and pH.

As pH is raised adsorption of individual ions (monomers and dimere) increase. Thus it is suggested that at higher pH values, provided the Krafft lemperature is not exceeded (26° C for dodccylammonium chloride), the adsorption of ions increases with pH to a point where the amine solubility limit is exceeded within the quartz-solution interface.

Feldspar minerals are formed uniformly and have stable quality. Potash feldspar and albite account for about 50-60%. Gangue minerals mainly include quartz, mica and iron-containing minerals. Generally, this type of ore deposits need to be processed by flotation to obtain feldspar concentrate. The main processes of beneficiation principles are: Crushing …
