How to Take the Impurities out of Gold | LEAFtv

Set the gold ore and a small quantity of lead in a cupel. Place the cupel in a blast furnace. Heat the mixture until the lead and gold ore liquefy. The blast furnace batters the cupel with hot air. The lead combines with other metals and forms oxide compounds that separate from the gold. This process works best with small quantities of gold ore.

Gold and Platinum Refining & Recovery Systems / Equipment

This process is excellent for silver and platinum group metals. Silver is recoverable using this process, but unfortunately, it will not refine the silver. We perfected this process back in the late 80s for other refiners to refine both gold and platinum group metals safely, while also reducing costs.

In the cyanide process for extraction of gold and silver from

Silver and gold are extracted by the cyanide process (Mac Arthur - Forrest process). After the preliminary crushing and concentration by froth floatation process, the ore (crushed auriferous rocks in the case of gold) is leached with dilute (0.4 - 7%) solution of sodium cyanide made alkaline by adding lime kept agitated by a current of air.

How Gold Is Refined: A Step-By-Step Guide - Pease Curren

Even once the gold has been extracted from the earth, it’s still in its raw form. It’s still just raw ore that requires processing before it becomes pure gold. First, the ore is crushed. It then undergoes a series of processes that will vary depending on the different elements and minerals that are mixed in with the gold ore.

PDF Processing technologies for gold-telluride ores

The presence of gold telluride minerals may render an ore refractory, the extent of this depends on the telluride mineral present and the mineralogical association [3]. Gold, silver, and gold/silver-telluride minerals in ores dissolve more slowly than native gold in cyanide solutions, which results in less efficient gold extraction [4].
