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.
How to Refine Gold: 2 Major Techniques of Gold Refining,

Gold Refining | From Gold Ore to Doré | World Gold Council
From ore to doré. More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore,
Smelting and Roasting Ores to recover gold, silver and,
The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.
What is the best method for extracting gold from quartz,
Answer (1 of 5): How do you get gold out of quartz rock? Fairly simple * Crush the rock to a powder, using a ball mill or similar * Dissolve the gold, using potassium cyanide, mercury, or other solvents * Drive off the solvent to leave gold metal * Further refine by
