Liquid feeds may be supplied from bulk storage tanks, intermediate bulk containers or standard drums with delivery pumps to suit. For multi batch operation systems the weigh hopper can discharge into an intermediate holding vessel situated beneath. From the holding tank the liquid is pumped on demand to the downstream process.
From there the loaded carbon may be acid washed to remove material, such that might interfere take longer for the carbon stripping process. After the acid wash, the acid is neutralized with NaOH. Then the carbon is sent to the carbon stripping process. This can be either at atmospheric pressure of a

01/05/2011· The rate of adsorption of gold cyanide onto activated carbon is very slow by normal industrial standards, and it can take weeks or even months to attain true equilibrium loading.
As Scott explained, Cyanide's drawbacks were too numerous. Waste treatment and cleanup were a constant problem and expense. The cyanide is insidious, said Scott. Despite your best precautions it creeps everywhere and gets into everything. The noxious fumes created by cyanide, especially in the summer, required costly venting. The cyanide plating lines needed close monitoring because
The control of liquid levels, for example in a process tank, is an important function. An example would be a hot water tank where water is removed, perhaps for washing down, and the level needs to be restored ready for the next wash cycle. Control of water level and alarms for steam boilers is specifically excluded from this Module, and the reader is referred to Block 3 The Boiler House

The Sodium Cyanide NaCN plant produces HCN from methane, ammonia and air. The HCN is then reacted with caustic soda 50 NaOH to produce a sodium cyanide liquor of approximately 30 32 NaCN. The liquor is purified and diluted to 30 for sale.
The choice of the load cell is made from a finite selection of available load cell capacities 200, 300, 500 lb, etc. once the overall load requirements are determined. As a result, it may be necessary to use a load cell or multiple load cells to handle 750 lb of total weight. The live load portion of this is only 26.7 of the load cells total capacity.

Minimizing cyanide consumption will result in cost savings and improved overall process efficiency. BrainWave monitors the cyanide concentration exiting the leach tanks and manipulates the cyanide flow at the inlet of the tank stream in order to maintain a constant cyanide concentration. Deficient oxygen amounts slow the leaching speed.
If head tanks are used, the overflow must proceed back to the tank of origin. By this means, solution strengths can be corrected by re circulation. Screens for the removal of oversized materials should be included at appropriate points in the system. Reagents which are staged to flotation are usually added by means of a cup and disc feeder located at the appropriate position along the
