Biomining metal recovery from ores with microorganisms

Biomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from low-grade ores is the most important industrial application and a significant part of world copper production already originates from heap or dump/stockpile bioleaching.

Ore StockpilingWhy are we doing this again

 · Such stockpiles will only grow as large as the operator allows them to grow. At any time the operator can process the material and deplete the stockpile. Be aware that mining operations might still be mining other ore types then those ores may need to be stockpiled during the campaigning. That means even more ore stockpiles at site. 2.

Ore Grade Reconciliation TechniquesA Review

 · The essence of ore grade reconciliation is to identify analyse and manage variance between planned and actual results in a way that highlights opportunities. A consistent record of poor reconciliation is an indication that this variance has not been adequately managed. This would inevitably result in significant economic impact on mining companies.
