Whether the use of sodium cyanide leach gold mine or the use of a new type of non-toxic leaching agent leaching gold production, must be simple or detailed or mineral leaching test. The purpose of the leaching gold ore test is to find out the ore properties of the gold ore in detail and provide a scientific basis for comprehensive recovery of mineral processing. Providing the best beneficiation process and plan for the ore, providing the best balance point process plan for saving investment in process transformation, rationally controlling the cost of mineral processing, and improving economic benefits, providing the best leaching index for gold, and transforming the process of the concentrator And the new concentrator provides a scientific design basis.
(1) Study on the properties of raw ore
Rock ore identification of the ore, a detailed understanding of the composition, structure, structure, grain size of the mineral and the relationship between minerals and gangue and harmful elements. Understand the mineral characteristics of the mine, as well as the types and relative content of useful minerals, gangue minerals. Understand the particle size characteristics of the useful minerals of the mine, including the mineral size and particle size distribution characteristics of the mineral. Learn about the mineral and gangue mineral structural and structural characteristics of the mine, including the mineral size and particle size distribution characteristics of the mineral. Understand the embedding properties and inlaid relationships of the useful minerals and gangue minerals of the mine and the particle size composition of useful minerals and major gangue minerals.
(1) Spectral analysis of raw ore
(2) Multi-element analysis of raw ore to determine all recyclable elements and harmful elements.
(3) Perform phase analysis on gold to guide the determination of the beneficiation process and beneficiation index.
(4) Determination of true density and false density of raw ore.
(5) Determination of the hardness of the ore.
(6) X-ray diffraction analysis of the ore.
(7) Determination of the grindability of the ore.
(8) Determination of grinding fineness curve.
(9) Different size screening of raw ore is carried out to determine the composition ratio of different particle sizes in the ore, which provides a basis for design and transformation.
(II) Detailed conditions test of the beneficiation process
Carry out detailed grinding fineness test, determine the best grinding fineness according to factors such as production cost, ore dressing investment, ore dressing index, and find out the influence law of grinding fineness on leaching.
(1) Perform a detailed sodium cyanide dosage test to determine the optimum amount of sodium cyanide.
(2) Perform a detailed lime amount test to determine the optimum amount of lime.
(3) Perform a detailed leaching time leaching time test to determine the optimum leaching time and find out the influence of leaching time and leaching rate.
(4) Perform a detailed cyanide-free leaching test to determine the feasibility of replacing cyanide leaching with cyanide-free leaching.
(5) Carry out detailed non-toxic immersion gold dosage test to determine the optimal dosage of non-toxic immersion gold.
(6) The amount of detail co-infusion test for leaching of carbonaceous ores containing arsenic and other hard, the optimum amount of promoter determined the infusion.
(7) Perform a detailed non-toxic leaching time test to determine the optimal leaching time and find out the influence of leaching time and leaching rate.
(8) Perform a detailed leaching concentration test to determine the optimum leaching concentration.
(3) Analysis of the nature of the tailings.
Multi-element analysis of tailings, phase analysis of gold in tailings. Through the study of the properties of the tailings, the composition of the tailings is identified, and the analysis of the gold in the tailings is still useful. If it has the value of recycling, continue to recycle the tailings to achieve the best recycling benefits.
The ore dressing test plays an extremely important role in on-site production and construction. A reasonable non-toxic gold leaching agent is determined through simple mineral processing test to maximize economic benefits.
