Gravity concentration is the separation of minerals based on differences in specific gravity A gravity concentration process is designed to recover very high grades of valuable ore material into very small mass The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact.
Small Portable Gold Process Plant
This arrangement and flowsheet of a Mini Portable Gold Processing Plant permits several mineral separations by flotation and provides for the possible recovery of other minerals by gravity concentration The flowsheet is ideal for a pilot-plant in field testing of ores to determine the economic feasibility of an ore deposit prior to the installation of a larger plant or for processing ore.
Historically, mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles, and thereby increase the gold recovery rat Large-scale use of mercury stopped in the 1960s However, mercury is still used in artisanal and small-scale gold mining (ASGM), often clandestine, gold prospecting.

Gold Mining Process Development
The prospector’s gold pan is the most familiar gravity concentration device To function properly, the ore must be broken down to particles small enough to provide a significant specific gravity difference among the particl Placer mining has generally been where gravity concentrates have been most widely applied In a placer deposit, there.
Large-scale use of mercury stopped in the 1960s However, mercury is still used in artisanal and small-scale gold mining (ASGM), often clandestine, gold prospecting It is estimated that 45,000 metric tons of mercury used in California for placer mining have not been recovered  Business Small operations.

Method of Gold Extraction using Borax -Small Scale Miners
The Gravity-Borax Method GBM is still unknown to most Artisanal and small-scale gold miners (ASGMs) worldwide as most still use mercury to extract gold “Whole-ore amalgamation” is a technique that requires the use of 10-25 g of mercury to produce 1 g of goldWithin the last eight years, it has become evident that this technique is more widely used than earlier anticipated, and artisanal.

How efficient are they really? A simple testing method of
May 01, 2017· A simple testing method of small-scale gold miners’ gravity separation systems , Understanding and verifying miner’s ore-processing activities is key to appropriate interpretation of this study’s results For example, the miners at the site in this study reported that they used mercury, but that they only used it when they “cleaned.
Gold Extraction and Recovery Processes
Gravity Concentration Gravity concentration processes rely on the principal that gold contained within an ore body is higher in specific gravity than the host rocks that contain the gold  Elemental gold has a specific gravity of 193, and typical ore has a specific gravity of about 26 All gravity concentration devices create movement.
These processes can be classified as either density separation or gravity (weight) separation In dense media separation a media is created with a density in between the density of the ore and gangue particl When subjected to this media particles either float or sink depending on their density.
» The Basics of Successful Gold Mining-Part 1
The main problem in gold mining is in overcoming unknowns Until you find them, you do not usually know where the good gold deposits are located If it were really easy, all the gold would already be gone The fact that so much gold is being recovered by small-scale miners today proves it was not easy to find in the first place.
