The plant designed in 1966 by the Lanzhou Nonferrous Metallurgy Design and Research Institute, commissioned in 1980, the design capacity of 2000t / d, is typical of our complex multi-metal mineral processing plant. (1) The nature of the ore: Lead zinc deposit is Paleozoic metamorphic volcanic rock

The mine is a cassiterite multi-metal sulphide deposit. The ore body is layered, the inclination angle of No. 15 is below 35°, and the thickness of vein is 0.5~8m. Ore firm or medium firm, stone solid slate top and bottom, with a comprehensive mining law. The ore blocks are arranged along the s

1. Rare earth beneficiation Mineral processing is the use of different mineralization methods between the various minerals that make up the ore. Different mineral processing methods, different mineral processing techniques, different mineral processing equipment, the useful minerals in the ore are

Operating procedure 1. Before driving, first check whether the oiler and lubricating oil are full of lubricating oil. The special bearing must not be short of oil. 2. All fasteners and fastening bolts should be carefully checked for tightness. 3. If the rotating belt is good, it is found that th

The methods of extinguishing natural fires of sulfide ore can be divided into active methods, negative methods and combined methods. The active method can directly cover or act on the pyrometal ore by using water, inert substances, etc.; or directly excavate the spontaneous combustion ore. This me

Changes in the composition of lead oxide zinc ore variety, ease of beneficiation vary widely, affected by the mud of ore, degree of oxidation, its performance and determine alternative process flow, it has a great influence. This paper will present the results of a beneficiation process for a highl

“The harvest period of corn is long and the farming time is not anxious. If there is time or manual picking, this saves money.” In the just-concluded autumn harvest season, Ding Lin, a farmer from Xilaozhuang Village in Wuyi County, did not have a choice. It is understood that

Here is a brief introduction to the various excavation mechanisms. The chain bucket gold mining vessel is currently the most commonly used one. Its excavation mechanism consists of a series of buckets. The loops of the bucket are used to excavate and raise the ore and discharge it onto the ship fo

Sodium sulfide is a strong base weak acid salt. As flotation adjusting agent, which other lead ore, sphalerite, yellow copper ore, bismuthinite was inhibited. For example, in the separation of copper- molybdenum mixed concentrate and the separation of molybdenum-niobium mixed concentrate, Na 2 S-pr
