COSTS AND COST ESTIMATION Chapter

The capital costs and operating costs of a mining project will be influenced by many factors that must be assessed before costs can be estimated for a preliminary feasibility study. The most important factor affecting costs is the size of the mine and pro­ cessing plant as expressed in terms of tons of ore mined and milled per day of operation. 6.3.2.1 Mine Size or Production Rate After ...

Underground hard-rock mining - Wikipedia

Underground hard-rock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and lead.It also involves the same techniques used to excavate ores of gems, such as diamonds and rubies. Soft-rock mining refers to the excavation of softer minerals, such as salt ...
