A classifier equipment with overflow end spiral completely submerged below the liquid surface.
Xinhai tailings dry stacking technology is mainly applied to the dewatering and concentrating of mineral tailings in the mineral processing plants. To reach the aim of tailings dry stacking and avoiding environmental pollution, it is the essential technology of green mine.
Phosphate Flotation Product Line is applied for complex structure phosphate with fine particle distribution, closed embeddedness relationship, difficult monomer dissociation, etc.
Barite is fragile and like a big tube. The separation methods of Xinhai are generally gravity separation, magnetic separation and flotation.
Alluvial gold processing solution mainly applies to processing alluvial gold with a large volume of gangue minerals. Alluvial gold processing is a set of mining processes, including crushing and screening, desliming stage, separating stage, etc.

The exact date that humans first began to mine gold is unknown but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria.The graves of the necropolis were built between 4700 and 4200 BC indicating that gold mining could be at least 7000 years old. A group of German and Georgian archaeologists claims the Sakdrisi site in southern Georgia dating to the 3rd or
Lowergrade sources of iron ore generally require beneficiation using techniques like crushing milling gravity or heavy media separation screening and silica froth flotation to improve the concentration of the ore and remove impurities. The results highquality fine ore powders are known as fines. Magnetite. Magnetite is magnetic and hence easily separated from the gangue minerals and
Copper ore mining districts now danced to Swanseas tune. They sent agents to the town to sell their ores direct to the smelters. At first it was just English Welsh and Irish mines that supplied the ores but from the late 1820s the lifting of tariffs on imported ore transformed this HibernoBritish trading network into a genuinely global
Placer mining involves washing metals minerals and the gemstones from streambeds with a water cannon. Plant material from swamps. Match the percentage of energy we are saving when we use recycled materials rather than using ore or other raw material sources to produce various materials. Roughly 50% energy savings Steel

Other gold mines use underground mining where the ore is extracted through tunnels or shafts. South Africa has the world's deepest hard rock gold mine up to 3 900 metres (12 800 ft) underground. At such depths the heat is unbearable for humans and air conditioning is required for the safety of the workers.
