The process yields concentrates containing roughly 30% copper, which are sequentially fed to a smelter, a furnace in which most of the some iron and sulfur are removed, then to a converter or converting furnace, where most of the remaining iron and other impurities are removed.

Best practices: Drilling and blasting : Pit & Quarry

Dec 07, 2015 The traditional method of drilling and blasting is to treat the two items as separate processes. A driller comes in to drill a hole; a blasting company puts explosives in the hole and blasts it. If you keep these two items separate, you cannot always achieve the best results. It’s not “chemical crushing,” as [Hissem] and I call it.

Abrasive blasting

Micro-abrasive blasting is dry abrasive blasting process that uses small nozzles (typically 0.25 mm to 1.5 mm diameter) to deliver a fine stream of abrasive accurately to a small part or a small area on a larger part. Generally the area to be blasted is from about 1 mm 2 to only a few cm 2 at most.
