Industrial types and characteristics of alluvial gold

Alluvial gold deposits widely distributed variety, its distance transport distance is usually divided into five categories: residual, talus, alluvial riverbed impact and shore placer deposits, which is more common in alluvial river bed. By their nature can be divided into wind power business into alluvial gold deposits, ice and water into the alluvial gold deposits into the alluvial gold deposits. Its handling is divided into different age deep alluvial gold deposits, terraces alluvial gold deposits and flood alluvial gold deposits.

Alluvial gold deposit width is generally 50 ~ 300 meters or more in width, length up to several kilometers or even tens of kilometers, buried depth is generally 1 to 5 meters, there are deep to 20 ~ 30 meters or deeper. The thickness of the gold deposit is generally 1 to 5 meters, individual up to 10 meters.

Gold in the alluvial gold mining in the multi granular, flaky, there are branches in morphology, the particle size of gold is generally 0.5 ~ 2 mm, but there are particles of gold powder bulk gold weighing several kilograms and is. The fineness of gold is usually 50% ~ 90%, the proportion of 17.6 to 18.

Alluvial Gold Mining Equipment

Alluvial Gold Mining Equipment

There are many kinds of mineral processing method of Alluvial gold mining, the gravity separation can be used as a alluvial gold ore dressing method indispensable, depending on the type and nature of the Alluvial gold mining is different, also different mineral processing equipment. The commonly used alluvial gold mining of gravity concentration equipment mainly jig and shaking, as the most professional jigging machine manufacturers, Shanghai SBM on alluvial gold mining on the jigging machine to do a brief introduction:

Jigging machine for alluvial gold ore beneficiation equipment is one of the main methods of gravity concentration, belonging to the deep trough sorting operations. The process is characterized in sieve plate will be continuous to ore jigging chamber, forming thick material layer, called the bed. Through the sieve drum into the rising water cycle, the bed layer rises loose, then flow to drop (or stop rising). In this process, the density different particle generation relative transfer, heavy minerals into the lower layer, light material being transferred into the upper layer, respectively, to obtain the concentrate and tailings discharge.
