Rock blasting for mining - SlideShare

An optimum blast is associated with the most efficient use of blasting energy in the rock- breaking process. The mine blasting expenditure should also be very less. 19. 19 The process should not only reduce the blasting cost but also reduce the consumption of explosives, and less wastage of explosive energy in blasting.

Copper Smelting Process - Furnaces Used, By-Products, and ...

Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal being compromised ...

Blasting Vibration Control Using an Improved Artificial ...

Blasting is currently the most important method for rock fragmentation in metal mines. However, blast-induced ground vibration causes many negative effects, including great damage to surrounding rock masses and projects and even casualties in severe cases. Therefore, prediction of the peak particle velocity (PPV) caused by blasting plays an important role in reducing safety threats.
