Chute Feeder
Chute feeder is a kind of feeding equipment which is earlier used in storage trough and it is suitable for the short-distance transport of metallic and non-metallic materials.
Leaching, oftengold, is theprocessof extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, ofgold, it is theprocessof dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes ...

Hongxing rod grinder is especially suitable for crushing river gravel to make sand. It's a kind of effective and energy saving rod grinding machine.
Ceramic sand kiln is one kind of calcining kilns which is a rotary cylinder machine used for calcining all types of materials.
In the metallurgical industry, shaker table is mineral processing equipment used for sorting fine material.
The hammer crusher, also named heavy hammer crusher, crushes by the collisions between high-speed hammer and materials. It has features of simple structure, high reduction ration, high efficiency, etc.
A rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object.
Electrometallurgy involvesmetallurgical processesthat take place in some form of electrolytic cell. The most common types of electrometallurgicalprocessesare electrowinning and electro-refining. Electrowinning is an electrolysisprocessused to recover metals in aqueous solution, usually as the result of an ore having undergone one or more ...

RUBISOV et al.: FUNDAMENTAL KINETIC MODELS FORGOLDORE CYANIDELEACHINGalso been reported for other oxidativeleaching processes, e.g. copperleachingin ammoniacal solutions [ 171. It is also interesting to note that the Habashi formula (34) may be considered as a special case of the more general KKW formula (30).

Forgold leaching, thekineticsmay be empirically described as a second-orderprocesswith respect to thegoldcontent of the ore and a first-orderprocesswith respect to the free cyanide concentration, as in the following lumped kinetic equation (de Andrade Lima, 2001; de Andrade Lima et al., 2002):
Oct 20, 2014· These reactions must be carefully managed and where possible suppressed to prevent excess cyanide consumption causing the process to become uneconomic. Leach Kinetics: ThepH and the temperature of the reaction can affect the kinetics of the gold dissolution reaction. However the pH and temperature will also affect the kinetics of other deleterious reactions (like those outlined above), …
One example of aleaching processthat uses vatleachingisgoldcyanidation, theprocessof extractinggoldfrom low-grade ores. In thisprocess, a dilute solution of sodium cyanide (NaCN) is used toleachthe Au into solution. The concentration is usually 0.01-0.05 % cyanide, or 100-500ppm.

1) Vat Leaching: Also known as “agitated tank” leaching, the lixiviant comes into contact with the metal material in large vats or tanks, which can be stirred, enhancing thereactionkinetics. The metal containing solid, such asconcentrate,ore,residue, orslag,often undergoes size reduction via crushing and grinding prior to leaching.
