Introduction

Washing, grading de-sludge

The grade of SiO2 in quartz sand decreases with the finer grain size of quartz sand, and the grade of impurity minerals is opposite. This phenomenon is especially obvious in quartz sand containing a large amount of clay minerals. Therefore, the quartz sand ore before the selection is carried out. Washing and de-slipping are very necessary.

 

Scrub

Scrubbing is the removal of the thin film iron and muddy impurity minerals on the surface of the quartz sand by mechanical force and the grinding and peeling force between the sand grains, and further smashing the unassembled mineral aggregates, and then further purifying the quartz sand by the classification operation. There are two main methods: rod scrubbing and mechanical scrubbing.

 

Flottion

The separation of mica and quartz is difficult, and it can be obtained by using an anion collector under acidic conditions or an anion-cationic collector under alkaline conditions. Generally, after scrubbing, deliming, magnetic separation and flotation, the purity of quartz sand can reach more than 99%, which basically meets the demand of industrial sand.

 

Sour

Dilute acid has a significant effect on the removal of iron and aluminum, while the removal of titanium and chromium is carried out by acid leaching with concentrated sulfuric acid and aqua regia. Usually, the mixed acid composed of the above acids is used for acid leaching of impurity minerals. except. The control of various factors of acid leaching should be based on the final grade of quartz, to minimize the acid concentration, temperature and dosage, in order to achieve quartz purification at lower beneficiation costs.
