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.
Sublevel Caving. Sublevel caving is a largescale mining method suitable for large ore bodies with a steep dip. The setup is similar to longhole stoping except loft raises are not required. Also mining starts at the top of the ore body and progresses downwards in a safe sequence.
Tardan Operations and Production Total 12m 2020 gold production was 953 kg (30 629 oz) an increase of 50% compared to 635 kg (20 407 oz) in 12m 2019. During 2020 the Companys main source of

Mining is a geotechnical industry. Geologist explore the economic mineral deposits for mining. A lot of methods are adopted to exploit the valuable economic mineral resources through open cast
Surface coal mining generally involves the following sequence of unit operations (1) clearing the land of trees and vegetation (2) removing and storing the top layers of the unconsolidated soil (topsoil) (3) drilling the hard strata over the coal seam (4) fragmenting or blasting the hard strata with explosives (5) removing the blasted material exposing the coal seam and cleaning the top of the coal seam (6) fragmenting the coal seam as required by drilling and blasting (7) loading
major caving methods are Longwall mining Sublevel caving Block caving Longwall mining is used in horizontal tabular deposits (mainly coal) while the others have applications in inclined or vertical massive deposits a lmost exclusively metallic or nonmetallic. Because the exploitation openings are intentionally destroyed in the

PDF version. There are four main mining methods underground open surface (pit) placer and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels beach sands or other environments.
