A visit to assess the technology used in Builsan was undertaken and the project would like to highlight the innovative thinking of the ASMers in dry processing for duplicating the Keene dry sluice using local material and be able to achieve economic gold recoveries. The dry washer is a good piece of equipment which needs some miner improvements. The dry washing has limitations that fine gold is blown away with the fine dust. There is lost of dust released to the working environment and this creates an occupational hazard. Please download more information. 

Gravity concentration equipment including wet and dry washing seperators, sluicem centrifugal separator, and fine gold recovery concentrator was produced and tested by a mining company 'CONRES' Co LTD. They were tested in artisanal mining sites in Bumbugur, Jargalant and Altan Us Sums of Bayankhongor Aimag and Narijn Teel Sum of Uvurkhangai Aimag. The equipment provides increased gold recovery rates and reduced gold loss in tailings and dust in dry washing areas. 

Additionally, the SAM Project in cooperation with professors and researchers of the Mining School under the Mongolian University of Science and Technology in Ulaanbaatar developed a general rule on ASM occupational safety and made an assessment of the current ASM technical and technical conditions in the country.
