  • Laboratory Gold Ore Chlorination Testing Procedure

    Experience has shown how difficult it is to obtain information regarding laboratory tests in connection with the chlorinationprocess 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 field.. The ore chosen was a partlydecomposed porphyry extremely siliceous and

  • Prepare Gold Ore Sample for Laboratory Testing

    If enough ore is available a laboratory Wilfley table may be used. For small lots of ore a gold pan or a small laboratory jig such as the mineral jig is convenient and gives reasonably good results. Sufficient concentrate should be prepared so that the various methods of treatment as already noted can be tried.

  • Cyanide Leaching Of Gold Laboratory Bottle Tests

    Gold Cyanide Solution Laboratory Bottle Test Method This is one method for doing cyanide bottle leaching tests for determining the 'leachability' of gold and silver by leaching with cyanide. Take the ore to be leached and crush it to a size that will fit into a pulverizer (usually 1/4"). Then feed the ore to a pulverizer and grind to 100 mesh.
