The study by Villares et al. [6] presented a copper bioleaching process that is comparable to the parallel process in our LCA, and the authors also compare their results to data from Ecoinvent that they used to evaluate copper pyrometallurgy. They found that the bioleaching process with 10 % PD. Conclusions

As with the water-based process, pyrometallurgy generally involves three steps: Roasting: ... In addition, tin, copper, and lead ores are smelted. Refining: In refining processes, metals are sorted by exploiting their chemical and metallurgical properties. The separation of metals is achieved by smelting in furnaces at high temperatures.

Grinding and drying/de-watering- In the wet process, additives (olivine, dolomite and/or limestone depending on the end product) are ground and then added to the ore slurry, typically at a level of 3 to 3.5%, before de-watering. In the other process after hot grinding, the material is re-wetted in paddle-type mixers and combined with additives.
