- Flow Sheet Of Copper Refining
After fire refining, copper is cast to anodes and aqueous electrorefining is used to recover these valuable elements. While largely effective, this later step is the slowest of copper production, and costly. 4 Auxiliary processes are required to handle and treat by-products, but the conventional

In refining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizing smelting in order to eliminate the common impurities, most of which have a stronger affinity for oxygen than has copper.In these operations some of the copper is oxidized to cuprous oxide …

These 8.7 Mt can be roughly split into two general processing routes for the recycling of copper scrap: smelting followed by refining, and direct melt (green flows in Fig. 1).Smelting and refining can recover copper from a multitude of different waste materials with a broad variety of material and elemental compositions.

Most copper smelters of today run with essentially continuous smelting step and use batch-wise operating matte converting and blister copper fire-refining steps. The smooth linking a continuous (Flash Smelting) and batch (Peirce-Smith matte converting) steps at the smelter requires accurate

The refining of the copper melt was performed over a wide temperature range of 1373–1573 K by varying the flow rate (0–3 m 3 /h) of the mixture and the partial pressure of oxygen (5–21 kPa). For the deoxidization of the melt, performed at the end of the refining process, a Cu–P ligature was used.

The conventional treatment of copper–gold concentrates involves smelting, converting, and electro-refining to produce a copper-cathode product. The conventional treatment of copper–gold concentrates does elicit some compelling reasons to seek an alternative hydrometallurgical process for the recovery of concentrate values.
