Streak Test. You can use your fingernail to make an indent to see if there's a yellow streak. Gold is soft and easily scratched with a fingernail, but other minerals are more rigid and hard. Using a streak plate, scrape your specimen over the plate, applying firm pressure. The streak should be a yellowish-gray color.

Ore-dressing methods fall naturally into two general subdivisions— (1) concentration methods and (2) direct-recovery methods (amalgamation and leaching or wet methods). Concentration methods are employed to remove worthless gangue material and concentrate the valuable minerals of the crude ore in a smaller bulk.

The Mercury Problem in Artisanal Gold Mining. Mercury-based artisanal and small-scale gold mining (ASGM) causes more mercury pollution than any other human activity. 1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold.

The more gold, the faster the process. This is because it is the friction of gold against gold which facilitates the cleaning process. Once the gold is glittery, rinse the soapy water out of the jar, pour the gold into a small (metal) finishing pan, and heat it up (outside and down wind) until the gold takes on a deep, natural, shiny luster.
