Journey of Gold

For secondary mining operations, miners typically use hydraulic mining, power shovelling and dredging. These techniques help to collect gold nuggets washed downstream, rapidly sifting out unwanted sand or gravel. Miners then wash the gold and ship it to mills.

How we process and recover gold

South Deep's milling circuit consists of a single-stage semi-autogenous grinding mill (SAG) and a pebble crusher for primary milling, followed by secondary milling using two overflow ball mills. These mills are essentially rotating drums that have steel balls inside which grind the rock into particles that are finer than 0.075mm in size.

Gold Extraction

Having treated on gold extraction with mercury by amalgamated plates and their accessories, something must be said about secondary modes of saving in connection with the amalgamation process. The operations described hitherto have been the disintegration of the gold-bearing …

Gold Extraction & Recovery Processes

In order words the process must work as a secondary process. The main parameters that affect the amalgamation process are lack of liberation, gold surface contamination, and mercury degraded. Dredging: Dredging is an underwater excavation performed to recover gold from placer deposits.

Secondary Deposits – GOMIAM

Small-scale gold mining mostly takes place on secondary deposits. This is also called placer mining. The gold lies under a few meters of organic material, sand and clay. On secondary deposits, pumps and motors are used. The soil is removed with a water hose of 2", 4" or 6".

The Journey of Gold

There is also a large secondary source of gold: the recycled gold market. This is gold that has been previously refined, and can come from a variety of sources including high-value sources like jewellery, catalytic converters and circuit boards. It's also far more environmentally friendly than mining for new gold.

Different Types of Gold Mining Processes

By-product mining: Extracting gold as a secondary product in mines primarily designed for other minerals. Open-pit mining: Large-scale excavation of surface areas to access gold ores. Heap leaching: Using chemical solutions to dissolve gold from low-grade ores on a heap leach pad.
