A study of the ASM sector of Ghana established the practices and\udattitudes of gold miners and proposed an alternative to mercury amalgamation.\udThe study showed that miners were aware of health hazards associated with\udmercury but continued to use it because they knew of no credible alternative.\udIt was realised that any process to replace amalgamation must be very efficient\udto capture gold around 50–100 μm. To be acceptable to the miners the method\udmust be: easy, quick, cheap, transparent and suitable for processing small\udbatches of concentrate. Direct smelting was selected as the technique of choice
