Arrastras Illustrated in These Historical Photos
The Mexican arrastra (also "rastra" or "arastra") was the earliest type used during the California Gold Rush in the 1850s. Simply constructed, these devices consisted of a flat track of stone inside a low wall of rock or wood forming a basin to hold the ore, and center post and horizontal shaft made of wood (often just a small tree trunks).
A Poor Man's Method of Smelting Gold | Sciencing
Smelting gold usually involves high-tech and high-cost tools to perform. Mostly, mining companies do the procedure, which sees one material bonded to or released from another in the presence of extreme heat. However, prospectors, and people at home, can smelt their old gold using some simple steps.

There are four main types of tools for separating black sand …
Improved siphon for separating gold from crushed quartz
The object of the invention is to draw off the water at its surface in the trough where the quartz is undergoing the process of crushing, which portion of the water contains the finely-pulverized quartz and fine gold in suspension, and in drawing on said water to separate by amalgamation the gold from the foreign substances.
PARTING: Separate Gold and Silver by Melting
Parting is the separation of silver from gold and a process during which the base metals are separated from both, but, as the presence of a high percentage of these base metals is injurious to the successful conduct of the processes which are chiefly in use, a preliminary refining by one of the methods already described is usually necessary.
Flotation | Mineral Processing, Separation & Beneficiation
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to
Gold Parting using Nitric Acid
If the gold zinc alloy be made according to the formula Au. Zn.4, the amount of zinc to be added need only be 1.3 to 1 of gold. If sodium were used the alloy Au. Na4 would have only one-half the sodium as the gold. In this case also the high atomic volume of the sodium would serve to separate the molecules of gold further from each other.
