    2016-3-24 · Thanks mr butcher and all members, Yes Gold is visible in Ore,i have study the Hokes book but he didn't explain how to refine gold from Ore. As my Sample containing 4.5% oF gold and other metals such as Copper and Silver as well.

  • how remove copper ore gold refine in pakistan

    2020-12-8 · May 22, 2018· You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off.

  • Refining of blister copper

    2011-8-19 · The copper anodes from fire refining are placed in a tank filled with solution of copper sulphate to which is added some sulphuric acid as electrolyte. The cathodes are pure copper starting sheets suspended between the anodes. Anodes are connected to the positive and catho-des to negative terminals of the source of current. On

  • Copper Smelting and Refining Process Pan Pacific

    After about 10 days of electrolysis, the cathode is lifted out and stripped from the stainless steel plate, resulting in the completion of refined copper (with grade of 99.99%) as a final product. The refined copper is shipped in stacked bulks, which are 1m in length and width and approximately 80kg in weight.

  • How to Calculate Grade and Recovery with Examples

    2021-3-2 · If the copper ore contains 40 tons of calcite gangue, we can also say 40% of calcite in the ore. A gold deposit with a grade equal to 5 g/t (gram per ton) means that in one ton of the ore, we have 5 grams of gold. You can calculate the ore grade by dividing the valuable mass by the entire ore’s mass (see the formula
