As one of the most common minerals in the earth's crust, quartz sand is widely used in glass, ceramics, metallurgy and other industries. However, natural quartz ores are usually accompanied by a large number of impurities. In order to improve the purity of quartz, it must be treated by flotation and other mineral processing processes.
Quartz sand beneficiation technology aims to extract high-purity quartz from silica raw materials to provide high-quality raw materials for downstream industries such as glass manufacturing, electronics, optics, etc. Due to the complexity of silica minerals, the beneficiation process requires multiple steps to remove impurity minerals and finally obtain high-purity quartz raw materials.
As the resources of easily processed gold ore are decreasing, refractory gold ore has gradually become the main ore source for gold production. The so-called refractory gold ore refers to gold ore with low total recovery rate of dressing and smelting, poor economic benefits, and process technology subject to environmental restrictions. This type of gold ore usually has a complex material composition and contains metal components that are difficult to extract.
As an important mineral separation technology, magnetic separation can not only effectively improve the recovery rate of non-ferrous and rare metal ores, but also optimize resource utilization and reduce production costs. Especially in the selection process of heavy-selection rough concentrates such as vein tungsten ore, vein tin ore, placer tin ore and seashore placer ore, magnetic separation technology has demonstrated its excellent separation ability.
