1979-7-9 · The reactor pressure is 15 atm(abs) and the reactor temperature must be 1250°C to assure complete conversion of carbon in a brick-lined vessel. Coal is ground to minus 100 mesh and conveyed to one of two lock-hopper feeders, which can be alternately pressurized with C02 to allow feeding into the pressurized reactor.

THE TEAS GRAPH Given the awkwardness of presenting three-component data, Jean P. Teas devised a triangular graph in 1968, on which polymer solubility areas could be drawn in their entirety. Because of its clarity and ease of use, the Teas graph has found increasing application in problem solving, documentation, and analysis, and is an excellent .

Labortory and pilot plant studies have shown that 80-90% of the silver and 60-70% of the gold can be recovered by: (i) leaching zinc calcine with spent electrolyte at pH 2.0-3.0 to generate a precious metal-bearing zinc ferrite residue. (ii) leaching of the thickened zinc ferrite with 3-5 giL thiourea solution in a sixstage carbon-in-pulp circuit.
