Alluvial gold mining methods

Jul 17, 2020 The principle of the alluvial gold mining process is to recover gold and all kinds of associated heavy minerals from raw ore as much as possible by the gravity dressing method. The lower limit of the particle size of gold recovery by gravity separation method is generally 0.01mm

    Gold mining was rough, physical work. Where alluvial gold was very rich, it could be obtained with a shovel and pan. However, pans were used mainly for prospecting. Simple machines known as cradles (often made from wooden liquor boxes) were rocked back and forth – the heavier gold collecting on matting on the cradle base

    Jan 28, 2017 In addition to the under level in our deepest and most difficult alluvial mines, an upper level should be constructed in the bed-rock, for three very important reasons. First, to provide an escape for the men in case the mine should be flooded; secondly, as a return air course; thirdly, to tap the water by boring, at a higher level, where the pressure would naturally be lightest
