A Poor Man's Method of Smelting Gold - Sciencing

To cheaply smelt your own gold you need to have access to a high temperature furnace. For a do-it-yourselfer this shouldn't pose a huge challenge. The first thing to do is determine the amount of gold to smelt. This will inform the size of the furnace. Small tin coffee cans or large trash cans make for good starting points in this regard.

Aluminum oxide "A" is 0.3 micron in size and Aluminum "B" is an extremely small micron size of 0.05. To put this into perspective, 50,000 grit is .5 micron and 100,000 grit is .25 micron. When we purchase a bar of red, white or green rouge we have no idea of the amount of oxide used or the size of the particle used in manufacturing the bar.

Ore processing – Waihi Gold

Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along ...
