The volume of aeration tank is calculated for the selected value of q c by assuming a suitable value of MLSS concentration, X. . VX = YQq c (S O S) 1+ k d q c Alternately, the tank capacity may be designed from. F/M = QS O / XV. Hence, the first step in designing is to choose a suitable value of q c (or F/M) which depends on the expected winter temperature of mixed liquor, the type of ...

the basis of reactor selection and design for bioleaching processes. Special attention is given to the influence of oxygen and carbon dioxide mass transfer, process stoichiometry, solids suspension and slurry homogeneity, and the use of bioreactors in gold mining. It is concluded that the future of reactors in biomining is promising and that new appliions, such as the bioleaching of copper ...

The design for each tank is described in chapter 4 and onwards. Chapters 4 and 5 call for general requirements of structural design of tanks and their supporting structures for water storage tanks and silos, respectively. Chapters 6 calls for requirements of seismic design

The leaching reactor is a stirred tank, and the basic design parameters are: geometry, construction material, design and loion of baffles and, design of agitator . Maintaining the pilot plant equipment geometry, the leaching reactor is made up of vertical cylindrical jacketed stainless steel AISI 316 vessel with a torispherical bottom and up heads and a central agitator to avoid vortex.

In leaching, ore which has been ground to pulp is placed in agitated tanks with sodium cyanide solution and gold and silver is dissolved into the slurry solution. The leach may require 24 to 72 hours to complete, and after the leach is completed, the leached slurry is routed to the CIP circuit. In CIP, adsorption of gold and silver onto activated carbon is completed in agitated tanks with ...

To assist the leaching kinetics oxygen will be injected into each leach tank. After leaching the pulp will pass through six 300 m3 CIL tanks. Each CIL tank will have ...

Selecting a contactor 1. Contacting pattern: Towers approximate plug G/plug L; bubble tanks approximate plug G/mixed L; agitated tanks approximate mixed G/mixed L Towers have the largest mass transfer driving force and in this respect have an advantage over tanks. Agitated tanks have the smallest driving force. FluidFluid Reactors: Design

Agitated leaching intermediate to highgrade, chalcopyrite concentrates are deposited in a tank and leached using mechanical agitation. (Experimental only) The raw material type also determines the type of microorganisms involved: Waste dump leaching uses mesophilic (ambient temperature) microorganisms,, bacteria.

Copper recovery using leach/solvent extraction/electrowinning technology 65 (Figure 2) and a alytic amount of LIX 63, was introduced in 19657 and in March 1968 the first commercial copper L/SX/EW operation, the Bluebird plan of Ranchers

 · Mixing tank design for heat transfer appliions has much in common with tank design for liquid blending appliions. However, in heat transfer appliions, a heat source (or sink) is installed in the mixing tank. These may be pipe coils, plates or the mixing tank may be jacketed. Jacketed mixing tanks are almost always round and usually used when scraped wall agitation is expected. However ...
