Basic requirements for mineral processing experiments (1) Spectral analysis. Identify the approximate content of various elements and the presence or absence of rare elements and other elements for comprehensive recovery. (2) Multi-element analysis or full analysis. Identify the content of major components, associated beneficial and harmful components in the ore. Chemical analysis of the properties of the slurry is also carried out when necessary to determine soluble salts. (3) Analysis of test funds . Find out the types and contents of gold, silver and other precious metals (including precious metals such as gold and silver). (4) Microscopic identification. Identify the ore type, mineral composition and content, ore structure, mineral size and embedding characteristics and symbiotic relationship. The analysis of the minerals selected for the purpose of mineral processing. (5) Phase analysis. The state of occurrence of the main useful components of ore and associated beneficial and harmful components, ie their different forms of mineral production. For example, copper ores for an assay NATURAL copper sulfide content relative primary, secondary sulfides, oxides and salts such as copper; ore for an iron assay magnetite, hematite, siderite, hematite, relative content limonite, pyrite, pyrrhotite, and iron silicate of titanium ore or the like. (6) Particle size analysis. Through the sieve analysis and water analysis, the ore particle size characteristics and the respective grain fraction content and metal distribution rate of the primary slime are determined. If necessary, use different concentrations of heavy liquid to determine the yield and metal distribution rate of each fraction according to different density, which provides a basis for heavy liquid separation. (7) Heavy wave separation. In the ore and rare metal ore of tungsten, tin , lead , zinc , iron, etc., if it is possible to separate most of the gangue without fine grinding, heavy liquid separation test should be carried out to provide for heavy medium pre-selection test. in accordance with. (8) Determination of physical and mechanical properties of ore. Density, loose density, angle of repose, internal friction angle, friction coefficient, hardness, viscosity, moisture, specific magnetic susceptibility, electrical conductivity, mud content, etc. of the ore were measured. (9) Other necessary analytical research content.
