In general, higher purity ores help increase hot metal yields in the blast furnace, and also lower production cost by reducing the amount of coke required. For these reasons, the rule of thumb is "higher Fe grade, higher price." Iron ore also differs in physical form.

Phytomining and Bioleaching GCSE Triple Award Revision

Metal ores are a finite resource which are in limited supply.New methods of copper extraction exploit waste ores and low grade ores.

How to profit from lowgrade gold mines Part 1 Kitco News

Eg. if the overburden is 100m thick and the ore is 50m, the strip ratio is 2:1. The lower a strip ratio, the more profitable the mine will be, since less material needs to be moved. Highgrade gold contained in narrow veins that snake through the rock can only be mined by excavating shafts and hoisting the ore to surface via low tunnels (drifts).

Chemistry: metals Flashcards Quizlet

in phytomining, plants can absorb copper ions from lowgrade copper ore as the grow. This could be on slag heaps of previously discarded waste from the processing of copperrich ores. Then the plants are burned and the metals can be extracted from ash. The copper ions can be "leached" (dissolved) from the ash by adding sulphuric acid.

The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.
