Eco-friendly and reagent recyclable gold extraction by iodination
The electrodeposition method was used to recover gold from the iodized leaching solution. The gold recovery rate reached 99.25%, and the current efficiency was 75.67%. Based on the redox principle, solid iodine was generated in the anode area during the gold recovery process, and the recovery rate of iodine was about 83%.

In 2005, up to 7 000 SSGM in Diwalwal were recovering less than 500 kg of gold. The basis for this figure is that the government, in 2003, recovered 41 kg gold on the 15% of extracted ore paid as tax [16]. A minor part of the SSGM does not pay any tax. In 2005, there were 371 establishments with mills [15], each establishment often

Production of Gold
The Ball Mill, B-101, grinds the 0.25” ore until it is in the range of 160 microns. The ore leaving the ball mill is sent to six hydrocyclones that separate the larger particles from the smaller particles. The top stream leaving the cyclone is 75% of the feed into it. This top product is 160 microns or less.

Difference Between Sag Mill vs Ball Mill
SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.

Mill leaching: a viable substitute for mercury amalgamation in the
Replacing mercury addition with cyanidation in ball mills was implemented in one artisanal gold mining operation in Portovelo, Ecuador, achieving 95% of gold extraction in 8 h of mill leaching. This technique demonstrated a drastic improvement in gold recovery. It was found to be a simple, inexpensive technique well accepted by local miners.

Ball Mill Question
Since the balls basically come in one size, and I haven''t measured them, they are about 3" diameter. There are sources for small milling balls for milling pigments and small batches in small ball mills i.e. bench-top mills. Balls wear down and smaller (worn) balls can be found on the market or discarded around old mill sites.

Optimizing and evaluating the operational factors affecting the cyanide
In order to find the optimum conditions of gold leaching with the highest rate of extraction (gold recovery), numerical optimization was carried out using DX software, which is demonstrated in figure 7. It was found that the maximum gold recovery could be obtained of approximately 91.5%, with a desirable value of 100%, by numerical optimization.
