  • Effective bioleaching of low-grade copper ores: Insights

    1. Introduction. The copper mine industry is facing with the need to process low-grade ores using low-cost technologies to meet global demand unceasingly (Faramarzi et al., 2020).As an economical and environmental friendly method, bioleaching has been exploited to liberate metals, such as copper, iron and nickel, from low-grade ores in some mining area (Panda et al., 2015).Iron ore pricing explained Metal Bulletin,For example, the daily, weekly and monthly indices are listed because of the varied liquidity displayed by different parts of the market. Sinter fines and lumps make up the bulk of the seaborne iron ore market, and are the products most frequently traded on a spot basis, so daily pricing is used for the key 62% Fe, 58% Fe and 65% Fe fines, and lump premium references.
