Main factors affecting heap leaching

Gold containing ore heap leaching may be of the type of ore, the mineral composition, the chemical composition, structure, configuration, storage and quality and other factors. The ore suitable for heap leaching must have sufficient permeability, large porosity, loose porosity, low content of impurity components which are favorable for cyanidation, clean surface of fine gold, and minimum of mud. However, whether gold-bearing ore is suitable for heap leaching depends on a number of factors. A feasibility study is often required before industrial production to determine whether the ore is suitable for optimum process parameters during heap leaching. At the same time, experimental tests and extended tests should be carried out to determine the optimum crushing particle size, concentration of leaching agent, consumption of leaching agent, amount of saturated solution required, type of protective alkali, concentration and consumption, solution spray method, The basin, the infiltration time, the amount of washing liquid, the number of washings and the washing time, and the oxygen content of the solution. The design should also consider the size of the heap, the location of the heap immersion field, the material of the cushion, the pump and the reservoir, the position of the high pool, etc. The correct selection of the location of the heap leaching field and the use of favorable terrain can greatly reduce the capital investment.

PIM Dispersion Kneader

LINA PIM Dispersion Kneader (CIM & MIM)

Characteristics of LINA PIM Dispersion Mixer:

(1) The specification of rotor, top and down ram is optimized to ensure the dispersion effect and material`s physical properties reach the best result.

(2) Strong Abrasive Resistance

1. The rotor blades are made of imported alloy steel to ensure they are wearable and durable. The rotor shaft is nitrided by 38CrMoAL and HV950-1050 treatment, its depth of 0.6-0.75 mm, its fragility is not greater than 11 levels to make sure high hardness of rotor shaft, high carrying capacity, strong torque, Continuous axis and stable transmission.

2. All surface that has direct contact with the material is sprayed by tungsten carbide. The spraying equipment is imported from Germany, the spraying process is automatic, and the workshop is enclosing. Tungsten carbide alloy is imported, and the wearable level of its surface is 10 times higher than conventional hard chrome plating surface. The spraying process is under high temperature of 1500â„ƒ and the spray speed is at a supersonic speed to ensure the surface adhesion is as high as 75N/ cmÂ². The integrated technology has achieved the lead level in the world.
