4.5. An establishment of a rational mode of leaching of the oxidised molybdenum on the basis of mathematical modelling

Analyzing applied methods of extraction of the oxidised molybdenum [13, 75, 70, 89-91], we come to conclusion, chgo application kombinirovannoju The way based on leaching of a concentrate zhirnokislotnoj flo - tatsii, can be effective enough.
Distinctive feature of an offered exhaust-and-forced method is presence of operation of fatly - acid flotation to which tailings of a sulphidic cycle are subjected. First, for the account zhirnokislotnoj flotations considerably reduces - sja volume of a material which is supposed to subject to leaching and consequently, and the expense of reagents. Secondly, quality of an initial product for leaching since in a foamy product zhirnokislotnoj flotations extracts - sja over 80 % of the oxidised molybdenum containing in tailings sulphide - essentially improves ache flotations. Besides, the concentrate zhirnokislotnoj flotations is a material krupnostju 90-95 % of a class-0,074 mm, i.e. a class in which concentrates - sja 80-90 % ferrimolibdita. Hence, the problem of separation of fraction - of the carrier of the oxidised molybdenum also can be solved. From references [17, 36, 80, 84] it is known, that the basic variable factors influencing technological indicators about - tsessa of leaching, are: concentration of solvent; relation Т:Ж; krupnost a material; duration of leaching; solvent temperature. Results before the spent researches [35, 79, 98] have shown, that use as solvent of the oxidised molybdenum a chamois ki - sloty is the most expedient.
