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.
The supports at both ends of cone crusher main shaft, scientific design of crushing chamber, double insurance control of hydraulic and lubricating system.
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
To make gold soluble sodium cyanide NaCN is added and the The ore is ground and crushed and any free gold is extracted by use of gravity as it may be.
To make gold soluble sodium cyanide NaCN is added and the cyanide ion forms a complex ion with the gold. This complex ion, [AuCN2]-, is readily soluble.
The Management of Cyanide in Gold Extraction, by Mark J. Logsdon, Karen Hagelstein .. Gold mining operations use very dilute solutions of sodium cyanide.
Gold cyanidation is a hydrometallurgical technique for extracting . Hydrogen peroxide and basic chlorination can also be used to oxidize cyanide, although these approaches are less common.
There is currently mch interest in how extraction of gold and silver from ores with acidic thiourea solution compares with extraction using alkaline cyanide
