BF flotation cell has two types: type I and type II. Type I is improved as suction cell referring to model SF; type II is improved as direct flow cell referring to model JJF.
Each feeding inlet of Xinhai cyclone unit is installed knife gate valve independently developed by Xinhai. This valve with small dimension reduces the diameter of cyclone unit.

Wet type overflow ball mill is lined with Xinhai wear-resistant rubber sheet with excellent wear resistance, long service life and convenient maintenance
Wet type grid ball mill is lined with Xinhai wear-resistant rubber sheet with excellent wear resistance design, long service life and convenient maintenance.
Ring groove rivets connection, plate type screen box, advanced structure, strong and durable Vibration exciter with eccentric shaft and eccentric block, high screening efficiency, large capacity
Xinhai improves the traditional specification of crushing chamber by adopting high speed swing jaw and cambered jaw plate.
High-speed hammer impacts materials to crush materials. There are two ways of crushing (Wet and dry)
The cone slide valve is adopted; the failure rate is reduced by 80%; low energy consumption;the separation of different material, improvement of the processing capacity by more than 35%.
Cylindrical energy saving grid ball mill is lined grooved ring plate which increases the contact surface of ball and ore and strengthens the grinding.
20-30%. Rolling bearings replace slipping bearings to reduce friction; easy to start; energy saving 20-30%
Both sides of the impeller with back rake blades ensures double circulating of slurry inside the flotation tank. Forward type tank, small dead end, fast foam movement

An ore is an aggregate of minerals from which one or more minerals can be extracted profitably. Some unusual process must: uraninite uranium oxide.

This is type of mining is only possible if the uranium ore is near the surface The milling process involves crushing and pulverizing the rock into very fine
Nov 14, 2013 By 1912, nearly all of the uranium ore went to European firms. Meitner and her nephew, Otto Frisch named the process “nuclear fission.” In 1938 .. Arno A. Penzias, the Origin of Elements, Nobel Lecture, December 6,1978.
Most uranium ores contain about 1.5 to 10 lb of U3O8 per ton, i.e., roughly 0.1 to 0.5 % of U, and these are concentrated by a chemical process2. The ore is first
the mineral particles, then leached in tanks with sulfuric acid to dissolve the uranium oxides. The solution is then processed
There are two methods of extracting uranium: conventional open- pit or underground mining, or a chemical process of In-Situ-Leaching ISL. Conventional
After mining, uranium ore is transported to a nearby mill for processing. The first step is to crush the ore and mix it with water so that it can move through a series

Some 15 years ago the radiation of uranium was discovered by Henri Becquerel, and already been described in the Nobel Lectures of H. Becquerel, P. Curie and E. Rutherford. The best radium mineral is the pitchblende from St. Joachimsthal Austria which has for a long time been processed to yield uranium salts.
Aug 12, 2015 The question is: What will North Korea do with this uranium? Services Institute in London, even got a lecture on the subject from a North The mining and processing of such ore will be extremely expensive for the Koreans.
When uranium ore is found near the surface, generally less than 100 metres deep uranium is pumped to the surface, and then circulated through a processing
