Industrially, the purification of spodumene primarily employs four mainstream processes: flotation, heavy-medium separation, magnetic separation, and combined beneficiation.
Lithium mica is one of the key sources of lithium. The lithium extraction process typically involves first using flotation to concentrate the ore into a lithium mica concentrate, followed by the use of acid, alkali, salt or pressure leaching processes to convert the lithium into soluble lithium salts, ultimately yielding products such as lithium carbonate.
Conventional quartzite ore purification primarily involves hand sorting/color sorting, gravity separation, magnetic separation, flotation, and wet leaching.
Because natural potassium feldspar ore often contains iron-bearing minerals, mica, clay, and other silicate impurities, it is difficult to meet industrial requirements when used directly, and it must be purified through beneficiation. Currently, the most widely used potassium feldspar beneficiation methods in industry mainly include washing, magnetic separation, flotation, acid leaching, and combined processes of multiple technologies.
A gold processing plant is the core production line for efficiently extracting gold from ore. A complete gold processing system mainly includes four stages: crushing and screening, grinding and classification, separation and extraction, and dehydration and drying.
Depending on the production process, mica powder is primarily produced using two methods: dry milling and wet milling. These two methods differ significantly in terms of their characteristics, applications, and respective advantages and disadvantages.
Manganese ore is an indispensable key raw material in the metallurgical industry. In manganese ore beneficiation, single-process technologies are widely applied, primarily including washing, gravity separation, magnetic separation, and flotation.
The method of cassiterite beneficiation is closely related to its particle size. Coarse-grained cassiterite is generally processed using gravity separation; however, gravity separation equipment has limitations regarding the applicable particle size range. At the same time, cassiterite ore often contains complex associated components with similar mineral properties, making separation difficult.
Based on mineral composition and beneficiation difficulty, gold ores can be classified into six major categories: low-sulfide, high-sulfide, polymetallic sulfide, gold-bearing copper ores, gold-telluride ores, and gold-bearing oxide ores.
Gold mine tailings contain precious metals such as gold, silver, copper, zinc, and iron. Secondary recovery of these resources can significantly improve the comprehensive utilization rate of mineral resources. Currently, the main recovery methods are roasting, leaching, and flotation.
