at the run-of-mine (ROM) pad, dumping time at the ROM pad stockpiles, hauling time with ADTs unloaded, and queuing time at the loading point. For an optimal cycle time to be achieved, the abovementioned activities must be performing efficiently. Therefore, to optimize the cycle time, the constraining activity must be identified and mitigated.
Heap Leaching is an industrial mining process wherein large piles of mineralized ore are irrigated with various chemicals including alkaline, acidic, or cyanide solutions which leach the intended mineral out of the rock and into the solution.

Recovering valuable metals and minerals from run-of-mine (ROM) ore involves several stages of separation and processing. The increasing scarcity of higher-grade and easy-to-process ores, together with stricter environmental regulations, has led many mining companies to opt for advanced and more environmentally friendly mineral processing methods.
crushed or run-of-mine rock (or occasionally mill tailings) are leached with various chemical solutions that extract valuable minerals. The largest installations in terms of both land area and annual tonnage are associated with copper mines, where copper-containing minerals are irrigated with a weak sulfuric acid solution.
