authority on gold metallurgy, and the chlorine refining process was chosen specifically with a view to the rapid and effective treatment of large amounts of bullion. This process had been patented by Miller, Assayer of the Sydney Mint, in 1867 and used in Australia since 1872 in contrast to the Lon#173;
During the passage of the liquid through the charcoal filter, the chloride of gold is decomposed and the gold is deposited on the charcoal, which, when fully charged, is burnt, the ashes are fused with borax in a crucible, and the gold is obtained.
The Chlorination of Gold Ores. By Mr. Donald Clark,, The ideal method for extracting fine gold would be to dissolve 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
DSTs CLEVR Process TM uses sodium hypochlorite with a catalytic amount of sodium hypobromite in acidic conditions to put the gold into solution. Contact time is short, and the process operates in a closed loop. All chemicals are recycled within the circuit and, sea water is also suitable where available.

The new smelter has capacity 1 million tons per year and has available rising to around 2 million tons per year. As is known, AMNT has changed the form of mining license from contract of
Gold Chlorination Processes amp; Methods
The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about percent purity. The Wohlwill process increases purity to about percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution

In Liddells Handbook of Nonferrous Metallurgy, Vol. 2, 1945, there is to be found a very complete account of the uses of chlorine as applied to the recovery of gold and silver, in Chlorination Processes amp; Methods. Introducing the chapter entitled Chlorine Metallurgical Processes Liddell says: Chlorine as a metallurgical agent appears to have lost ground during recent years, and much
Millers Gold Chlorination process was introduced by Miller. The refining process employs chlorine gas, which passed into molten gold covered with a layer of borax and silica, and reacts with most of metals present in the molten charge. Platinum group metals do not react. Basically, gold is slightly attacked in the first moments and all the chlorides formed rise to the surface and are
After sufficient leaching, the pregnant solution will be pumped to the carbon adsorption column for catching the free gold. The barren liquid will be pumped to the cyanide solution pond for recycle usage. The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again.

Chlorination may be done by addition of chlorine gas plus sodium hydroxide to pH 10 to produce sodium hypochlorite (NaClO). Chlorine gas treatment is about half as expensive as direct addition of sodium hypochlorite, but requires special handling equipment. Time of oxidation is usually 30 min to 2 hr (Crowle, 1971). The wastewater should be continuously agitated to avoid solid cyanide precipitates, which may
