| contents | A new still for the prevention of mercury poisoning in small-scale gold mining by amalgam extraction J. M. Pinzón R. Contreras C. Bernardy Ciencias de la Tierra Small Colombia amalgam method scale gold extraction A system for the recovery of mercury in small-scale gold mining in Colombia has been designed and tested. Distillation ofup to 300 g of gold amalgam takes ten to 20 minutes, and more than 90% of the mercury formerly lost in the atmosphere isrecovered for recycling. The equipment pays for itself and may be locally built using available materials. It has been widelyaccepted by miners because of the improved safety to miners and their families. The furnace can be fueled either with gasoline orLP gas. It may also be used for smelting small amounts of gold, thus getting rid of the sponginess which detracts from marketability.The new system is popular in Colombia because of the improved safety to mine operators. 2003 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56842407 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.4 Vol.42 |
