The AMIRA Metal Accounting Code of Practice and Guidelines (2007) has established best practice in process plant metal accounting. The code is based on the check in, check out concept; sampling the mass flow of the commodity of interest (e.g. gold) as it crosses a Transfer of Custody boundary.
Gold was subjected to the gravity concentration device in its coarsest state, i.e., as soon as a particle was discharged from the mill it saw the gravity concentration device. There were also some disadvantages: The gravity circuit had to process 3 or 4 times the new feed rate to the mill .
Plant benchmarking may comprise a full plant audit with historical review and process modelling. Systematic sampling across the mill will provide mass, constituent and water balances, and a careful look at plant survey data will help identify bottlenecks and opportunities for process optimisation.
A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

This chapter discusses process simulation in the gold industry. The many advantages of constructing a computer simulation model of a operating gold plant are described. Different areas of a gold plant require different types of simulation model, and these are discussed, together with some insights into the differences in the relevant software.
1 Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.
Here is an Ancient Gold Ore Milling Process used in China in the 1800s. We might use it again after WW3. At the time, 1890, the Author said "There is, of course, nothing for us to learn from this imperfect and rudimentary gold-extraction process described here, which is doubtless destined to disappear ere long, before the progress of scientific mining, now making itself slowly felt ...
It is routine in a processing plant to sample the feed, tailings and product streams in order to make a metallurgical balance – to account for the metal processed and where it ended up. For gold plants, measuring and estimating the amount of "goldin- circuit" (GIC) or gold inventory is also important.
Gold Plant Mill Process Sampling. We are a large-scale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment.
It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The primary operations are comminution and concentration, but there are other important operations in a modern mineral processing plant, including sampling and analysis and dewatering. All ...

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 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.
