Blasting caps come in a variety of types, including non-electric caps, electric caps, and fuse caps. They are used in commercial mining, excavation, and demolition. Electric types are set off by a short burst of current sent by a blasting machine via a long wire to the cap to ensure safety.
Dynamite is considered a "high explosive", which means it detonates rather than deflagrates. The chief uses of dynamite used to be in construction, mining and demolition. However, newer explosives and techniques have replaced dynamite in many applications. Dynamite is still used, mainly as bottom charge or in underwater blasting. References
Toxic chemicals are used in the Flotation Process to separate the copper and molybdenum out of the milled powder. This Flotation process is the major extraction method at Duval/Sierrita mine because of the poor quality of the copper at this site. Some chemicals produce bubbles that that the copper adheres to and the "bad stuff" falls to the bottom.
Types of explosives Explosives can be classified into one of four large categories: primary, low, high, and nuclear explosives. Primary explosives. Primary explosives are generally used to set off other explosives. They are very sensitive to shock, heat, and electricity and, therefore, must be .

Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of .
Dynamite Background and Raw Materials. Dynamite is a commercial explosive used mainly for demolition and mining. Invented in 1866 by Alfred Bernhard Nobel (1833-1896), it is more accurately described as the packaging of nitroglycerin, a highly poisonous explosive liquid, or other volatile compounds such as sensitized ammonium nitrate. Dynamites can be packed in measured charges, .
Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay) and stabilizers. It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht and patented in 1867. It rapidly gained wide-scale use as a more powerful alternative to black powder.. Today, dynamite is mainly used in the mining, quarrying, construction, and demolition industries.
