02Manganese oxide ore and manganese carbonate ore are two main types of manganese ores in industrial production. Manganese oxide ore is mainly composed of pyrolusite, pyrolusite and manganese ore. The main manganese minerals in manganese carbonate ore are rhodochrosite, calcium rhodochrosite, manganese-containing calcite and rhodochrosite, etc.
Heap leaching gold extraction technology piles the ore on a special impermeable pad and then sprays it with a solution containing cyanide to dissolve the gold from the ore, and finally recovers the gold through steps such as adsorption, desorption and electrolysis.
The main methods for extracting lithium from lepidolite include lime roasting, sulfuric acid roasting, sulfate roasting, chlorination roasting and pressure cooking.
There is a lot of ore mud in weathered phosphate ore. Pre-demuding of semi-weathered and weathered phosphate ore can obtain higher-grade phosphate concentrate.
Fluorite beneficiation technology and equipment are crucial to improving ore grade and resource utilization efficiency. Fluorite beneficiation technology mainly includes crushing and screening, grinding and grading, and separation and purification.
