Portable Gold Processing Plant for Different Types of Deposit

Gold occurs in two types of deposits: lode and placer. Lode deposits consist of ore minerals in veins or series of veins or disseminated in rock. These deposits require blasting, milling, or chemical treatment to recover the gold.

When a lode deposit weathers and erodes, gold and other minerals that resist weathering remain. Some of these minerals are called ‘heavy minerals’ because a given volume weighs more than the same volume of most other minerals. Many heavy minerals are black and make up what are commonly referred to as ‘black sands’.

When the weathered material is transported in a stream, heavy minerals (including gold) settle into crevices and any other depressions in the streambed and form placer deposits. Gold in the sand and gravel in the streambed can be recovered by panning or washing.

Placer Gold Prospecting Machine

Prospecting for placer gold is normally done with a gold pan or similar instrument to wash free gold particles from loose surface sediment. Deeper placer deposits may be sampled by trenching or drilling.Geophysical methods such as seismic, gravity or magnetics may be used to locate buried river channels that are likely locations for placer gold.[3] Sampling and assaying a placer gold deposit to determine its economic viability is subject to many pitfalls.

Once placer gold is discovered, the gold pan is usually replaced by sluices or mechanical devices to wash greater volumes of material. Discovery of placer gold has often resulted in discovery of hardrock gold deposits when the placers are traced to their sources.

Portable Gold Washing Plant for Sale

Zenith portable gold washing plant is an effective equipmention gold processing application. It is easy to move on working site, and shows excellent performance to help refining high grade gold concentrates. If conditions do not allow you to deliver the pay-dirt to a nearby water site to be processed by wet methods, it need to consider processing the rich material by dry washing methods.

Dry gold washing plant apply an air blowing fan to blow a controlled amount of air-flow up by the dry material that is being processed. Air flows help blow off the lighter materials and allow the heaviest particles and gold to collect.
