So please no judgements against me. Upon my first effort to smelt gold powder into a bead, I seem to have lost the gold. What happened was I was given a rock of gold ore from Nevada. I know at least enough to know this was gold. I crushed the entire fist size rock all the way down to powder.. once thoroughly crushed, I panned it.

A rock is either crushed or ground, sodium cyanide (in a ppm level) is added to this rock, and gold reacts with the rock and is leached in the solution. A solution containing gold is reacted with activated carbon, activated carbon gets stripped to produce an enriched solution, and gold is plated in an electrowinning cell.

In contrast to placer sources, hard rock gold is taken from bedrock. To dig, blast, and move ore in hard rock mining, you need big, heavy tools. In "free milling," ore is broken down into a fine powder and mixed with water to make a syrup. Cyanide breaks down the gold in the slurry, which is then melted down to make bars.

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.
