ASTM E400 02 Standard Test Method for Analysis of Ores,

Withdrawn Rationale: This test method covers the spectrographic analysis of ores, minerals, and rocks for silver, palladium, platinum, gold and rhodium. The concentrations of precious metals which can be determined in the material being analyzed depend on the amount of sample assayed.


gold refractory,ore classification,preprocessing methods

If silver is the main economical mental, we can try to use medium preprocessing method, such as chlorination of ore or concentrate ore, soda leaching, and strengthening cyaniding leaching, if these methods were failed, it requires a more difficult preprocessing method if using cyaniding method for silver recovery, the preprocesses include roasting, pressurized oxidation, and microbacillary oxidation method. As for gold-silver ore, if gold
