Gold recovery with sluices can vary depending on several factors. Fine gold losses can be minimized by cleaning up more frequently, reducing the speed of the slurry flow to around 0.50 to 0.80 m/s., and decreasing the feed size by performing a previous screening. Some experienced operators have increased recovery by adding a liner to the sluice

INTRODUCTION. Mine dusts are products of mining activities which are formed when rocks are broken by impact, crushing or grinding. The compositions of these dusts are determined by its source region and closely reflect the composition of soil cover. 1 These dusts are made of minerals like feldspars, quartz, carbonates, sulphates and phosphates.

Use of Rock Crushers in Gold Mining . Unlike the alluvial gold found in river beds, most of the gold mined underground is found in hard rocks that contain a lot of other materials. To get pure gold from these gold-bearing rocks has to be processed. The first stage is to crush the rocks to smaller fine gravels that will allow for gold molecules

For most small-scale gold prospectors, crushing ore to determine the amount of free gold is the best method to determine gold content within an ore sample. Free gold can then be collected using traditional gravity based methods, which do not require the same level of permitting as the chemical methods used by commercial gold mines.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
