In Australia, 80% of gold is produced from open-cut mining with the remainder being produced from underground operations (IBIS World, 2012). However, other costs may be applicable to ISR compared with conventional processing (e.g., hard-rock fracturing, the use of an excess of reagents and bioreactor-related costs if bio-oxidation …

There are two economic sources of lithium; brines and hard rock ores. The majority of the global lithium production, greater than 60%, is produced from brines while lithium ores accounted for the remaining production (Ebensperger et al., 2005).Table 1 summarises the world's major lithium producers from ores and brines, and the total …

Froth flotation was studied as a lepidolite final upgrading stage and was found to produce high-grade concentrates. Before flotation, the material was sieved at 63 μm to remove very fine particles, which is a fundamental step in guaranteeing the success of the flotation process (Fan et al., 2013, Fornasiero and Filippov, 2017). Flotation …

The solution has been under constant development inspired by each new application. "For example, the early adopters were in the phosphate and potash business, which saw the positive results and the opportunities of classifying the feed to float multiple streams based on size, which is not common in hard-rock applications," Wasmund said.

Underground hard-rock mining accounts for 40 percent of global mining operations but only 12 percent of run-of-mine (ROM) production. 1 Run of mine is ore that is mined and crushed. In this article underground mining refers to underground hard-rock mining; thus, underground soft-rock mining, such as coal, is excluded.
