History of Explosives and BlastingHistory of Explosives and Blasting In the US and Canada alone, blasters use more than 6 billion pounds of explosives and 75 million detonators per year. Coal mining accounts for twothirds of consumed explosives of which more than 80% of it is ANFO.
The Methodology of Use of the Mobile CrushingandSorting ...This paper justifies the use of the mobile crushingandsorting radiometric complexes (MCSRC) under conditions of ironore pits in order to increase the ore quality produced in the mine faces of the «orerock» contact zone and stabilize the content of the useful component in the general oreflow. The patterns, which are used as a fundamental base of the radiometric sorting process, are given.

MichiganIronMinesThe Gogebic Iron Range extends for 80 miles from Lake Namekagon, Wisconsin, in the west, to Lake Gogebic in Michigan, in the west. Nathaniel D. Moore uncovered ore deposits in the Penokee Gap near Bessemer in 1872, but it was not until 1884 that the first iron ore shipment was made.
Iron ore miningThis saves mining operations multiple millions in USD every month since iron ore beneficiation increases significantly the costs per ton of ore. Control of the moisture content on the mining conveyor belt (NIR) together with accurate monitoring of the composition of iron ore before shipment guaranties constant ore quality to avoids penalties.
