Refining of Nickel Copper Cobalt Mattes by Pressure

05/06/2020 The process of smelting to produce matte rejects a large proportion of the iron, and the sulphur associated with it. When producing a matte for refining by these processes, the iron content can advantageously be lowered to the minimum consistent with good recovery of base metals in the matte

Pgm refining Johnson Matthey

Our refining process involves four key steps: Evaluation Evaluation is a critical stage. During this step we determine the pgm content of the material and agree with the customer on the pgm quantity or value we will return to them. At this stage we provide the lead time for refining. Material tracking is crucial; on receipt all customer batches are uniquely barcoded to ensure full traceability

One process is the ammonia pressure leach, in which nickel is recovered from solution using hydrogen reduction, and the sulfur is recovered as ammonium sulfate for use as fertilizer. In another, the matte may be roasted to produce high-grade nickel oxides; these are subjected to a pressure leach, and the solution is electro- and carbonyl refined.

Copper extraction

Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production). Davenport, et al, noted in 2002 that even then 80% of global primary copper production was from copper–iron–sulfur minerals and that the vast majority of these were treated by smelting. Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters were initially located near the mines to minimize the cost of transport. This avoided the prohibit
