 · The Moonlight ore contained the antimony mineral, stibnite, which was notoriously difficult to roast and cyanide, and a pilot plant was built to investigate the smelting of Moonlight concentrates by sintering, blast furnace smelting with lead and lead concentrates, and refining to obtain the gold.

Gold concentrates tend to be mostly iron, so they are also known as "black sands.". Gold concentrates are also made by grinding down ore, quartz, or other productive rock types into sand. This procedure is much faster and easier than panning, but the tradeoff is a final product that has less gold …

 · This type of ore is not a concentrate, it is a raw ore. It must first be crushed to powder to extract the gold. Rock crushing equipment will cost many thousands of dollars even if you purchase small scale crushing equipment from China - At least US $5,000 and more likely closer to US$ 10,000.

 · Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.

When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.

The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.

Ore concentrate, dressed ore or simply concentrate is the product generally produced by metal ore mines.The raw ore is usually ground finely in various comminution operations and gangue (waste) is removed, thus concentrating the metal component. The concentrate is then transported to various physical or chemical processes called hydrometallurgy, pyrometallurgy smelters, and …

gold ore concentrates it up to grams per tonne. A grade of grams per tonne gold was achieved from the coarse size fraction, with a recovery of, resulting in an upgrade ratio concFeed of the test result which recovered the most gold has a gravity concentrate grade of grams per tonne gold with a gold recovery of percent see table below

Processed ore becomes concentrates A large part of the ore mined is complex ore comprising several different metals. The ore is crushed to form several mineral concentrates which can then be processed into pure metals in our smelters.

gold ores can be classified into 11 types (Table 1). Some metallurgical implications to these gold ore types are summarised below: Placers, quartz vein gold ores and oxidized ores: Generally, placers, quartz vein gold ores and oxidized ores are free-milling and gold can be recovered by gravity and/or direct cyanide leaching.

Now, for a gold pan, a very good panner can take a pan with 15 pounds of ore in it and pan it in 10 minutes. That is 1.5 pounds per minute, versus 100 pounds in 7 minutes, or 14.3 pounds per minute. The table is 10 times faster than a gold pan using theoretical situations. In reality it is more like 20-30 times more efficient than a gold pan.

Gravity concentration tends to recover the pyrite with the gold, and only removes the lighter minerals, such as quartz, from the ore. The most difficult particles to gravity concentrate are the fines, and 75 microns to 2 microns are definitely very fine. So, even if the ore were ground to 2 microns, it may not be recoverable using current ...
