Analysis of CopperGold Ore with the Avio 220 Max ICPOES

The extraction of metals from ore at a mining plant requires the routine analysis of various samples. These include the feed (crushed ore), the tails (waste ore after processing) and the concentrate (final product). For a coppergold mine, the metals that require analysis can include, not just copper (Cu) and gold (Au), but also silver (Ag) if present at significant levels. Other .

AN INTRODUCTION TO COPPER EXTRACTION

The existing facility is able to extract a 94% grade of copper at a throughput of 25,000 tpa. However this copper is required to be further treated before it is suitable for commercial use. Due to the vast quantities of copper ore and the relative inefficiency of the Stage 1 plant, a Stage 2 upgrade has been initiated.

 · The optimal concentrations of gold leaching media to achieve potentially complete dissolution of gold from its ore in copperammoniacal thiosulphate media based on the effect of the investigated parameters were M S 2 O 3, 3 M NH 3, and M Cu 2+ with a desirability value equivalent to unity ( d = ). 1. Introduction

From Ore to Finished Product

4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction. The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6.

From Ore to Finished Product

Copper ore is extracted using two basic methods of mining open pit or underground mining. 3. Processing of Copper Ore The first step in processing the ore removed from the mine is to break the large rocks of ore into smaller pieces. This is accomplished by a variety of subsequent processing steps. 4. Beneficiation of Copper Ore
