tank vs. vat leaching db0nus869y26v.cloudfront in metallurgical processes tank leaching is a hydrometallurgical method of extracting valuable material (usually metals) from ore.. tank vs. vat leaching factors. tank leaching is usually differentiated from vat leaching on the following factors in tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped.innovations in copper mining extraction producingan example of this is codelcochile's operation, radomiro tomic, located near calama, chile. while a conventional oxide mineral leaching operation, this is the largest heap leaching operation in the world. radomiro tomic was built in 98 at a cost of us641 million for a design plant capacity of 0, metric tons of copper per .leaching efficiencies continue to improve in test work the calculated leach tank capacity required for leaching clay80 beneficiated concentrates was reduced to approximately one third of that of the bpd study, a more than 25% improvement on the previous test2 (table 1); residence time was the same as the previous test, one third of the bpd study (table 1); 1septic tank leaching chambernormal operation are small lot sizes, inappropriate soils, and shallow water tables. leaching chamber systems can be used only in areas with soils that have percolation rates of 0.2 to 2.4 minutes per millimeter (5 to 60 minutes per inch). neglect of septic tank and leachingfile size 9kbagitation leaching in parral tank systemmeans of effecting agitationanalysis of the pachuca tank and its operationsdefects of the systemthe parraltank system of slimeagitationextraction of valunclusionin the cyanideplants built before 07, agitation was effected in tanks 10 to ft. deep, and ranging in diameter up to 30 ft., by mechanically revolving stirringarms, assisted by centrifugal pumps drawing the settled pulp from the bottom of the tank and throwing it back on the top of the charge in the same tank. this method was fairly efficient, but expensive in both the construction and the operation of the plant; and it was superseded by pneumatic or airlift agitation, which proved to be at least equally efficient, aprocess equipment cost estimating by ratio and proportiontherefore, the 06 cost of the 2, gallon capacity vessel is estimated to be 1 9 ,005 . now, having determined the current estimated cost of the smaller capacity vessel, we need to adjust this amount to correspond to the larger volume (5, gallons). referring to table 1, we find a sizean analysis of capital cost estimation techniques forthis research serves to compare the use of the capital cost estimation software, aspen capital cost estimator (acce), with other capital cost estimating methods specifically the module costing technique outlined by richard turton et al. and also
