Base Metals Process Development and Optimisation Minteks expertise in developing and evaluating various process flowsheets for the recovery and refining of base metals encompasses all unit operations and process steps from the mined ore to the pure metal or metal salt. In depth research is conducted to assess and improve the latest technologies.
Gold equivalent is calculated by the same formula and assumptions used to report the JT Deposit NI43 101 Resource with metal prices of $1350/oz gold, $16/oz silver, $2.80/lb copper, $1.20/lb zinc, $1.00/lb lead and does not consider metal recoveries. Table 2.
The Wohlwill process increases purity to about 99.99 percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. Under the influence of an electric current, the casting functions as a positively charged electrode, or anode.

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.
High gold alloys typically contain a high percentage of gold, usually in the range of 80% to 85%. The alloy is strengthened with the addition of 7% to 10% platinum, and trace elements such as indium, zinc, and tin are added to provide an oxide layer for predictable porcelain bonding.
Doing metallurgical process development testwork and engineering is the best way to keep your final and total cost to a minimum. how to build a successful mining project Images for
HighGold Mining is a Canadian gold exploration company with highly prospective properties in Alaska and the Ontario Timmins Gold Camp. HighGold Mining is focused on two well known North American gold mining environments; Alaska and Timmins, Ontario to both establish and grow existing high grade resources.
Gold filling was a tradition popular up until the later 1960s, particularly in American cases, and involves using heat and pressure to bond a layer of gold alloy to base metal and then rolling it into sheet. A gold filled case can be seen as a sandwich made from a slice of base metal contained between two thinner slices of gold.
