  • Ore Mining and Dressing Effluent Guidelines US EPA

    What Is Ore Mining and Dressing?Rulemaking HistoryAdditional InformationMine operators extract ores (metal-bearing rock) from underground mines and surface mines using machinery, explosives and chemicals. Extraction processes include dressing (picking, sorting, washing of ores), milling (crushing, grinding, etc.) and beneficiation (processing to improve purity/quality).Wastewater is generated during the mining process from groundwater produced during ore extraction, from water used by operators for equipment cooling and dust control, and from precipitation

  • Different Types of Explosives Used in Mining

    Explosives are chemicals, and as such, they bring reactions. Two different kinds of reactions (deflagration and detonation) allow distinguishing between the high and low explosives. The so-called "low-order explosives" or "low explosives," such as Black Powder, tend to generate a large number of gasses and burn at subsonic speeds.

    This chemical binds to the surface of the particles as it is a surfactant. The main considerations in this chemical is the nature of the head group and the size of the hydrocarbon chain. The hydrocarbon tail needs to be short to maximize the selectivity of the desired mineral and the headgroup dictates which minerals it attaches to.

  • What is a high explosive?

    Low explosives are mixtures of chemicals that burn very rapidly, but subsonically (as opposed to supersonically), meaning that they “deflagrate.” They consist typically of fuel and an oxidizer. The black powder used in fireworks is one example of a low explosive. Black powder burns very quickly, but to get it to go bang, we have to contain it.
