·Direct Concentrate Processing Leaching A leaching circuit consists of five leaching reactors in series Fig 2 Atmospheric oxidative leaching conditions are used enhanced with sodium chloride addition 20 g Cl − /L corresponding to the seawater concentration thus enabling the use of saline seawater in the process The concentration of solids from the first
·In this research a procedure has been devised which rejects much of the pyrrhotite while maintaining the necessary level of talc rejection In batch tests on an ore containing pentlandite pyrrhotite pyrite and talc the procedure rejected 57% of the iron sulphides and 98% of the talc and recovered 81% of the nickel in a concentrate assaying % Ni
·Laboratory studies were carried out on the roasting of the bulk sulfide float produced from the uranium mill at Jaduguda in India assaying 11% Cu 7% Ni % Co and 3% Mo adopting a factorial
·Nickel ore mainly includes sulfide copper nickel ore and nickel oxide ore latterite nickel ore The beneficiation and processing methods of the two are quite different different beneficiation methods are selected according to the grade of nickel sulfide ore and then nickel is prepared in different ways; the smelting methods of nickel oxide ore are generally
·Subsequently the technical viability of the bulk copper nickel concentrate flash smelting route was established in two commercial scale campaigns that were conducted in the Copper Cliff copper flash furnace in 1985 and 1987 The Falconbridge Iron Ore Process operated at the smelter from 1956 to 1972
·One of the problems associated with polymetallic ore concentration is the separation of bulk concentrates which is difficult due to the textural and structural characteristics of mineral particles
Shandong 500t/d Copper Lead and Zinc Ore Bulk Flotation Project Ore Property Shandong client commissioned Xinhai Mine Research Institute to conduct ore dressing experiment after collected 50kg samples on the scene After tested the ore properties of sample ore Xinhai lab concluded that the main metal minerals of the project were copper lead zinc and a certain
·concentrates however a low grade bulk concentrate may be produced with reasonable copper and nickel recoveries Due to the capability of the CESL Process to handle bulk concentrates Teck Resources initiated studies to determine the amenability of the Mesaba bulk concentrate samples to hydrometallurgical testing
