How to Remove the Flour Gold From Black Sand Our Pastimes

Black sand deposits, which are composed of heavy metal materials such as iron and hematite, are common in areas where gold is found. While mining hobbyists typically regard the presence of black sand as an indicator of gold deposits, the sands themselves contain small particles of gold, called flour gold, and the sands are frequently processed for gold extraction.

Black Sands Processing « TCB Metals and Refining

We Process Black Sands. Due to the heavy iron content of black sands, most processors, smelters and refineries are unable to process them. We have a unique chemistry that allows us to aggressively process precious metals at 20 mesh and below in less than one hour, so we can effectively leach black sands without dissolving the majority of their iron content.

Dealing with Black Sands: getting all the gold out of your ...

The truth is that most of the values in black sands are simple free gold particles, which are recoverable by standard gravity recovery methods. Any values truly locked into the black sand, surrounded by minerals such as magnetite so that it cannot be recovered by normal gravity separation systems, are typically very small.

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 ...
