    Laboratory Gold Ore Chlorination Testing ProcedureGold mining

    Experience has shown how difficult it is to obtain information regarding laboratory tests in connection with the chlorination-process for the extraction of gold from its ores, and I therefore present the following method, somewhat in detail, for the benefit of those who may desire to pursue research work in this fieldPlacer mining is the technique by which gold that has accumulated in a placer deposit is extracted Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging.

    Diagnostic Leaching for Refractory Gold Ores

    A diagnostic leach test can be very useful to qualitatively assess how gold occurs within the ore and the extent to which it may be refractory Several different permutations of diagnostic leach tests depend on specific objectives, but they generally involve the sequential leaching of a gold ore sample with progressively stronger reagents .-01-04 How to Assay Gold The naked eye cannot determine the purity of metals This holds true for ore and jewelry alike In order to determine the percent composition of a sample of gold, the sample must be assayed Gold can be assayed in one of.
