Heat the furnace until it reaches a temperature just above 962 degrees Celsius. Maintain the temperature at this level and no higher. This is the melting point for silver. At 1,083 degrees Celsius, the copper would begin to melt as well. When the silver has melted and formed a pool in the bottom of the crucible, turn the furnace off.

It is shown in the diagram that copper is in solution at low pH in the form of the CuNO 3 + ion. For separation of copper and tin, tin must exist as a solid in this region and can be removed by filtration. The copper in the solution can be recovered by cementation from a sulfate bath. 2.

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.

You should find that copper has been reduced from +2 to +1; oxygen (in the gas) has been reduced from 0 to -2 (oxygen in the SiO 2 is unchanged); and three of the four sulphurs on the left-hand side have been oxidised from -2 to +4 (the other is unchanged). Once again, the sulphide ions are acting as the reducing agent.

Whether or not any precious metal was dissolved in the preliminary cyanide treatment was not stated. In another elimination method the copper mineral is dissolved out by means of ammonia after which the ore is cyanided as usual.
