Hardrock Mining TechniquesUnderground MinesMinings Method

Underground mining (hard rock) Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals such as those containing metals like gold, copper, zinc, nickel and lead or gems such as diamonds. In contrast soft rock mining refers to excavation of softer minerals such as coal, or oil sands.

Platinum Mining and Refining Education

Modern Platinum Mining Techniques. Most of the mining for platinum ore occurs deep underground. To extract the mineral-rich materials, miners pack explosives into holes drilled in the rock and blast it into smaller pieces. The broken rock is then collected and transported to the surface for processing. Platinum production in South Africa.

Panning is the most suitable method if you only have an amount of rock less than about 15 or 20 pounds. On the other hand if you are going to be processing large quantities of rock on a regular basis such as would come from the workings of a hard rock mine, you will need some sort of automated system to process your crushed materials.

Hard Rock Mining: The process Wells Historical Society

Initially the jump made gold mining a great venture in the 1930s, but the fixed price eventually discouraged mining because increasing inflation over the same period decreased the profits to the companies. Before hard rock mining operations even begin, companies explore areas where gold may be found and analyse the rock.
