Black Sands Processing & Content Assaying

It appears none of the gold prospectors spend nor time or money on assaying their black sands for gold value determination. Instead, they use a rare earth magnet to tells them what is in there and see that most of the gold is magnetite with sometimes hematite. What little remains goes under the microscope where I see that it is a mix of wolframite, scheelite and zircon. Could there be some ...

Extracting Gold | HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

Oil sands are a mixture of roughly 90 percent clay, sand and water, with 10 percent bitumen [source: Grist]. The dark, sticky sands look similar to topsoil, are viscous when warm and freeze as solid as concrete in cold temperatures. But calling them "tar" pits or "tar" sands is misleading -- the thick black substance isn't tar, but rather bitumen.
