The Chlorination of Gold Ores. - Digitised Collections

The Chlorination of Gold Ores. By Mr. Donald Clark, M.M.E., B.C.E. The ideal method for extracting fine gold would be to dis-solve out the gold with some solvent which would not attack other minerals present. The solvents known 6o years ago were chlorine, bromine, and cyanide of potassium. Yet in

Laboratory Gold Ore Chlorination Testing Procedure

16/02/2017  This large excess was due to the care taken to remove the last traces of gold chloride from the ore. These experiments, both laboratory and barrel, demonstrate the suitability of the ore for treatment by chlorination. The original ore assayed $26.25 in gold and $0.68 in silver per ton. Assuming the extraction obtained in the barrel-test to be 93.46 per cent., there was a loss of value of $1.74 in gold,

Chlorination In Extraction Of Gold

The processing of gold scrap varies not only with the gold content but also with the amenability of the gold in the scrap to extraction. Thus the bulk of the gold may be recovered by leaching techniques using cyanidation or aqueous chlorination and the residue . Experiment Of Gold And Silver Extraction From Cyanide. 3.2. Effect of Chlorination Time on Gold Extraction Experiment conditions the ...

How to Leach Gold Ore With Chlorination Sciencing

25/04/2017  Add your ore to a plastic-tub cement mixer along with 10 pounds of river rock and turn the mixer until the ore is 200 mesh or more. 200 mesh means there are at least 200 particles in one square inch of ore. Remove the river rock, which will still be large. Place the gold ore in the cement mixer. Pour in the hot water, bleach and HCL.

Newbery–Vautin chlorination process - Wikipedia

The Newbery–Vautin chlorination process is a process to extract gold from its ore using chlorination developed by James Cosmo Newbery and Claude Vautin. Background. The process of gold extraction from ores via its absorption in chlorine gas, from which it is reduced to a metallic state, is not a very new discovery. It was first introduced by Karl Friedrich Plattner around 1848, and at that ...

US5236676A - Pressure chlorination of refractory gold

A method and apparatus are described for recovering gold from aqueous slurries of refractory gold ores containing sulfidic and/or carbonaceous matter. The method entails pretreating an ore slurry with chlorine in a multi-compartment autoclave operated at an elevated pressure. The chlorine used in this pressure chlorination pretreatment can be in either the gaseous or liquid state.

Carbonaceous Gold Ore Treatment Method - 911

15/04/2018  The simplest method of treating a carbonaceous ore is the method described by R. W. Nice (1971) at the McIntyre Porcupine Mine where the carbon, which contains very little gold, is floated off and discarded. The remaining ore is then responsive to cyanidation. This does not work at Carlin because the carbonaceous compounds have a high gold content. A considerable amount of flotation work was ...
