Description of Mercury Ore Beneficiation:
Mercury is a chemical element with symbol Hg and atomic number 80. It is commonly known as quicksilverand was formerly named hydrargyrum. A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is bromine, though metals such as caesium, gallium, andrubidium melt just above room temperature.
Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigmentvermilion is obtained by grinding natural cinnabar or synthetic mercuric sulfide.
Mercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches,mercury relays, fluorescent lamps and other devices, though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favor of alternatives such as alcohol- or galinstan-filled glass thermometers and thermistor- or infrared-based electronic instruments. Likewise, mechanical pressure gauges and electronic strain gauge sensors have replaced mercury sphygmomanometers. Mercury remains in use in scientific research applications and inamalgam for dental restoration in some locales. It is used in fluorescent lighting. Electricity passed through mercury vapor in a fluorescent lamp produces short-wave ultraviolet light which then causes the phosphor in the tube to fluoresce, making visible light.
Mercury Ore beneficiation process often applies to mass and continuous production of Mercury ore.
A. Raw materials preparation:
Raw ores are sent to primary crusher by vibrating feeder, the crushed ores will be send to vibrating screen for separating. Under screen ores will be sent to powder silo. Upper screen ores will be returned back to second crusher by belt conveyor for re-crushing. It is named two step one closed circle crushing work flow.
Raw material from powder silo will be sent to ball mill by feeder and belt conveyor, ball mill discharges to spiral classifier, bigger size will be returned back for re-grinding. Overflow will be pumped to hydro cyclone by slurry pump for second classifier: bigger size will be returned to ball mill for re-grinding. It is named one step two closed circle grinding flow chart. Overflow from hydro cyclone will be sent to trash screen and thickener.
B. Leaching and adsorption:
C. Tail water treatment:
The tailings are lifted to the filter press, and the filter cake is so called tailings, which are transported by belt conveyor and truck to the yard, while filter liquor goes to circulating water tank for recycling
D. Gold-loaded carbon treatment:
The gold-loaded carbon is processed by Desorption&Electrolysis equipment in batches to get gold-dust. The gold-dust goes to gold melting furnace and turns to gold bar. The gold-loaded carbon after Electrolysis process could return to last stage in the flow chart for reprocessing.
1. Feeding Equipment --- Vibrating Feeder
Vibrating Feeder is suitable for feeding the massive, particle, ore power materials from crude-ore bin or intermediate bunker to the receiving unit evenly at a fixed quantity. With the features of being simple-structured, economical and practical.
It is widely applied to such industries as mining, metallurgy, cool, glass, machinery, light industry, chemical industry, power plant and food, etc.
2. Crushing Equipment --- Jaw Crusher
Jaw crusher is widely applied to various sectors like mining, metallurgy, building materials, highway, railway, and chemical industry, and it is able to crush various materials with compressive strength less than 320Mpa.
3. Crushing Equipment --- Cone Crusher
Cone crusher is widely applied in metallurgical, construction, road building, chemical and phosphatic industry. It is suitable for hard and medium hard minerals, rocks, iron ores, limestone, copper ores, platinum ore, hematite and limonite ore, magnetite ore, chromite ore, mercury, quartz, granite, sandstones, etc.
4. Vibrating Screen Equipment --- Vibrating Screen
Vibrating screen is used for coarse, medium and very fine at all levels, also can be used to for medium of materials as cement, etc. Self centering vibrating screen is widely used in mining, coal, metallurgy, building materials, refractory materials, light industry, chemical industry, medicine, food and other industries. It is an ideal equipment for crushing and screening unit.
