95 b) Jumper is the machine used to make small blast holes & it is more effective in boring a nearly vertical hole. c) Priming needle is used to maintain the hole while tamping is done & is in the form of a thin copper rod with a loop at one end. d) Scraping spoon is used to remove dust of crushed stone from blast hole. e) Tamping bar is used to tamp the material while refilling a blast hole. The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc., as well as for ore dressing of ferrous and non-ferrous metals. The ball mill can grind ores and other materials, wet or dry. There are two kinds of ball mills according to their ways of discharging material: grate type, and overfall type. Many types of grinding media are suitable for People also ask Are there any pre treatment options for refractory ores? Pre-treatment options for refractory ores include: The refractory ore treatment processes may be preceded by concentration (usually sulfide flotation). Roasting is used to oxidize both the sulfur and organic carbon at high temperatures using air and/or oxygen. Used as the flotation collector for non-ferrous metal complex sulphide ore with medium selectivity and strong flotation ability, which is suitable for polymetalic sulphide ore consisting copper, lead zinc and so on. In the natural loop, it is particularly effective in the flotation for various copper and pyrite. Discover the mine’s full-value 1.

See full list on 911metallurgist.com Working Principle EDX (Energy Dispersive Spectrometry) X-ray spectrometer is based on the principle of X-ray fluorescence (XRF). XRF principle: the atoms illuminated by high-energy X-ray emit X-ray spectra with a certain characteristics, the wavelength of which is only related to the atomic number of element, not X-ray excitation energy. Therefore, by determine the wavelength, we find what contained in the sample and start the qualitative analysis; by measuring the line intensity and comparing with a known sta System Components The instrument is constructed mainly by three systems: excitation system, optics system and detection system.
