4. Acid leaching method. If the finished quartz sand is reddish, and the iron and titanium content does not meet the product quality requirements, the acid leaching method can be used. Wash the quartz sand with water to remove powder and impurities, then carry out acid leaching before drying it.

Gravity separation is a method in which materials/minerals are separated based upon the difference in particles density [].Water as a medium is an important factor in improving the differential movement between various particles during gravity separation and eventually sorting different particles [].When water is removed, and air plays the role of …

The processing sequence for the recovery of gold, ilmenite, and zircon from the Moclips Beach sample is shown in figure 2. This sample contained more ilmenite and zircon per ton of sand than any of the other samples obtained from the sand and gravel plants. Analyses of products and distribution of major constituents are shown in table 9.
