Kalgoorlie Operations

The Kanowna Belle mine site is situated in the Eastern Goldfields of Western Australia, approximately 18 kilometres northeast of Kalgoorlie. Open pit mining commenced in 1993, with full underground production achieved in 1998. The Kanowna Belle operations were acquired by Northern Star in 2014.

Jewelry Making

Jewelry polishing is a multistage process whereby metal is buffed with soft rotary tools made from bristles, felt, or muslin. Applied in descending stages, from coarse to fine, wheels are charged with various polishing compounds to achieve the desired luster. If you would like to see the jewelry making process in person, you can visit our

Hard Rock Mining Gold and Silver Ore and processing it

In most gold ores, the final process to extract the tiniest gold particles is the use of cyanide to dissolve the gold. Cyanide, in the presence of oxygen actually dissolves both gold and silver. It is both efficient and inexpensive, so it is widely used in precious metal ore processing.

All About Gold

Gold mining describes the process of extracting ore – metal-rich rock – from the earth's crust. And, as with other minerals, there are a number of geological processes that are involved in forming these ore deposits. Modern gold mining predominantly takes place in areas where there is a significant concentration of gold-bearing ore (ore

How to Take the Impurities out of Gold

Put the crucible in a furnace. Heat to 1,100 degrees Celsius. Dross will rise to the surface. Periodically remove the crucible from the furnace and skim the impurities off the surface of the molten gold. Stir the gold after each removal of dross and before returning it to the furnace. Repeat this process until dross stops rising to the surface.
