Improvement of Low-Grade Silica Sand Deposits In Jeddah Area

Improvement of Low-Grade Silica Sand Deposits 119 Scrubbing the untreated feed sample (without flotation) upgrades silica content to 93.4% which is comparable with the flotation concentrate. Washing alone, without flotation, does increase the silica content to slightly less than flotation and scrubbing, but the iron content remains high.

Removing iron from silica in sand washing processing LZZG

The purity requirement of quartz sand in high-tech field is harsh: generally requires SIO2 content greater than 99.99%, impurity content, especially The content of iron impurities is limited to a very low range, so it is very important to increase the taste of quartz sand in the production process to reduce the content of iron. In silica sand, the main mineral is quartz, and it also contains some other impurity minerals.
