Gold

The tonnage of refractory ore to be roasted or leached is greatly reduced by first producing a finely ground concentrate. Ground ore or treated concentrate is placed in a weak solution of sodium cyanide, which dissolves gold and forms a slurry of gold-bearing solution and other solids. Some ores may be treated by heap-leaching. Get price

Palladium element extraction method

PLASMA SMELTING OF UNCONVENTIONAL ORES AND MINE

METHODS FOR EXTRACTION OF GOLD Gold ores that are less amenable to traditional extraction methods are classified as 'refractory'. Whilst 'free milling' ores typically have recovery levels above 95%, refractory ores have recovery levels significantly below this, with some only achieving 50% to 60% recovery (Vaughan, 2004). Many refractory Get price

Method For Processing Pyritic Concentrate Containing Gold

Abstract: Provided is a method for processing a gold-bearing sulfide ore which involves maintaining the ore in a substantially oxygen free environment, preferably beginning with comminution of the ore and ending when a desired final concentrate, enriched in sulfide minerals, is obtained by flotation.

In an average mine, how much ore must be processed to

Jan 20, 2019The first point to make is that there is no such thing as an "average mine", they are all unique, such is the nature of the natural world. Nonetheless, this I understand the general thrust of your question. There are two factors that need to be co Get price

Gold processing 101

If this ore also contains 1g/t Au (for GSR =1), and 90% recovery to concentrate is achieved, then 0.90g will be recovered and with a concentration ratio of 20 (5% to concentrate) this corresponds to 18g/t Au in concentrate. At current gold prices this is worth about US$600. Get price

Gold ore dressing method,beneficiation machine of gold ore

Refining gold ore concentrates

Sep 28, 2008Supposedly there is some gold in the sand. Most of those mining operators just look for the free milled gold and rely on gravity to remove it but I wonder if you were to take those concentrates and grind to a very fine mesh and then digest it and precipitate it out (or some other leach method), how much more gold can actually be gotten? Get price

Mineral Deposit Value

As you can see in the example above, the deposit does not have to be enormous in size (only 500 meters long by 100 meters wide) to contain a valuable deposit (approximately $6 billion worth of minerals). However, in order to be as realistic as possible about this valuation, you can not assume that the complete ore body contains the same grade (i.e. 2% copper and 1.5 gram per tonne gold). Get price

Modern gold deportment studies

A ''Modified Gold Deportment" is then performed on a concentrate, where the gold grains are pre-concentrated by gravity separation. This has similarities to the method described by Lastra et al.
