Assuming ideal conditions and a perfect core, the value of the hole (or the sample increment) would be determined by use of the following equation: cents per cubic yard = W x V x 27/A x D. in which W = weight of gold in milligrams. V = value of gold in cents per milligram. A = effective area of drive shoe in sq. ft.

Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4
International methods of sampling should be used to ensure that valid sampling procedures are applied when feed is being tested for compliance to a particular standard or objective. The Codex General Guidelines on Sampling – CAC/GL 50-2004 (FAO/WHO, 2004) provides information to facili-tate the implementation of these goals (Box 21).
Description . It is a machine specially used for the stripping of electro-refined copper cathode. The whole system consists of copper cathodes washing unit, stripping unit, conveying unit, stacking unit, cathode packing, and S.S. cathodes washing unit, edge strip tightening unit and conveyer trolley etc. . The whole working process of the machine is demonstrated as following.

Comprehensive sampling methods—the keys to maximum recovery of precious metals from your process or product T o accurately determine the amount of precious metals present in materi-als for recovery Sabin Metal's refining plants use three different sampling techniques. These are dry sampling, melt sampling, and solution sampling. Each of these
Secondary metal supplies fall into two general classes, new and old scrap. 4 The former refers to metal discards generated within an industrial setting, either at metals producers ("home scrap") or from metals fabricators ("prompt industrial scrap"). Because new scrap stays within the mill or factory, the quality (i.e. chemical composition) is generally well known and homogeneous.
Core sampling is used on sweeps materials which are in drums. To obtain the sample, a pip e i s driven to the bottom of the drum in a minimum of three locations, middle, edge, and halfway, in every drum. Then these samples taken from the location are blended and a representative sample is taken.
The 61,600-hectare Poplar Project hosts a current undiluted indicated mineral resource of 152.3 million tonnes grading 0.32 per cent copper, 0.009 per cent molybdenum, 0.09 gram per tonne gold and ...
It can also treat secondary material like scrap copper, WEEE/PCB/IC and etc. It is the optimal solution for small-capacity smelting up to far.The smelting process is given as follows: feeding – melting –drossing – flux adding – converting – drossing – sampling – refining and casting.
home scrap's availability is directly linked to steel production volumes. Typically, home scrap is fully and immediately recycled in the mill. 2. Prompt (or industrial) scrap. Generated in the downstream manufacturing process, prompt scrap rates tend to track finished steel consumption. Like home scrap, prompt scrap is usually fully recycled.
Because copper is an element, it can be infinitely recycled. New and old copper scrap or copper alloys can be melted, re-purified, and recycled into new components ~50% of copper used in the copper industry was recycled. In 2010, 770,000 metric tons of copper were recycled, at estimated value of $6 billion
