The invention discloses a method for producing high-purity quartz sand. The method comprises the following steps magnetic separation, floatation separation, staged de-sliming, acid-leaching washing, drying and finished product obtaining. Through magnetic separation, garnet, hematite, limonite, ilmenite and coenobium particles thereof are removed.
In the conventional process of oxygen pressure acid leaching of quartz ore, purication of quartz sand depends on acid attack to mica minerals, resulting in high acid consumption and a long leaching time 13. The two problems lead to signicant decreases in equipment life and production efciency, and an obvious increase in production costs.

Comparison of heap leaching results between sulfuric acid and hydrochloric acid with the same concentration 1 M can be seen in Fig. 6. The same concentration of the acid used in heap leaching produces a different PLS, where sulfuric acid produces PLS with a higher nickel ion concentration than hydrochloric acid. Fig. 6.
Heap leaching accounts for a fifth of global copper production, sourced primarily from porphyry ores, yet metal recoveries are often not optimal. Gangue, and its interaction with acid, plays an important role in such processes. Thus, a proper understanding of gangue minerals present in the ore, their textural relationships relative to particle size distribution, reactivity with acid under ...
