Erosion is the overall process and weathering is one of the contributing process Weathering includes a chemical process in contrast with physical erosion which is mechanical Weathering typically is a smaller scale process For example, rocks m.
The capital cost difference associated with Area 30 & 60 is 92% in favour of the 5,000t/d CVL case Further savings occur following year one, where leach pad expansion must occur with the base case The difference between the total process & infrastructure capital cost (pre-production) between the base case and 5,000t/d CVL case is a
What is biomining? | American Geosciences Institute
Dump leaching: low-value ore or waste rock is placed in a sealed pit and then bioleached to remove more of the valuable metals from the waste pile Agitated leaching: crushed rocks are placed into a large vat that is shaken to distribute the microbes and material evenly and speed up the bioleaching process
Vat leaching is carried out in vats ranging in capacity from 30 to 1200 tons Sand for leaching is separated from slime in cones, V boxes, classifiers, and in collecting vats filled by distributors—the overflow in each case being slime or finer portion of the ore As a rule, leaching is a simple process, involving a vat of well-mixed neutralized sand, ample contact with strong and weak .
