I use a technique of simmering the gold in HCl until the gold clumps and then filtering the gold from the liquor. This will, no matter how dirty the gold is, get you at worst 999 gold, usually 9999 gold. Always note that the base metals dissolved from the gold in the above method will dissolve some of the gold you are trying to clean.

The ores containing Native Gold erode due to weathering, and as the encasing rock breaks down, it produces Elluvial Placer Deposits (Bench Placer). These deposits form on the slopes of hillsides where a depression or wide level spot occurs downslope of the eroding In Situ (In Place) Hard Rock Deposit from which the gold is eroding from.

As simply as possible; where can I get ORE assayed? | Gold Refining

Depends on the ore, Lou. I processed one that ran in excess of 300 ounces/ton gold. Run the numbers on that and the 3% doesn't look all that unreasonable. It should be noted, in the ore I ran, gold was readily visible to the naked eye. I would expect that with 3% ore, it would be obvious. I wonder----was the ore in question from Colorado? Harold

Roasting and Incinerating

Roasting is a term you will normally see more often when discussing ore, and incineration when burning other materials. With ore sometimes they use the term roast, when they are actually talking about what I would call a fusion, like a roast with a salt like chlorides to make the gold dissolve easier in a later chloride leach.
