In this paper, 4-amino-3-thioxo-3,4-dihydro-1,2,4-triazin-52H-one ATDT was synthesized and introduced as a depressant for selective flotation separation of molybdenite from chalcopyrite. Its flotation performance and adsorption mechanism on minerals were first investigated by flotation, UV spectra, zeta potential, Fourier Transform Infrared Spectroscopy FTIR, and X-ray Photoelectron ...
Molybdenum Mo is one of the most important rare metals. It is a widely used additive in steel alloys, high-temperature alloys, and other materials 1,2.Mo usually occurs as molybdenite MoS 2 and is usually associated with copper sulfide ores such as chalcopyrite CuFeS 2 3,4.Mo concentrate is commonly obtained as a by-product from copper ore by a two-stage froth flotation technique .
A method and an apparatus for the separation of the mineral components of a pyrite containing copper- molybdenum ore by flotation. The method comprises grinding the ore in the presence of soda ash in an open circuit to produce an aqueous ore slurry subjecting the slurry to a collective flash flotation step 10 in the presence of soda ash and sodium sulphide to recover a first part of metal ...

A method of depressing copper sulfides and iron sulfides in a molybdenite floatation recovery process uses alkaline or alkaline earth potysulftdes at high concentrate pH. The method of enriching molybdenite content from a slurry having molybdenite and at least one of iron sulfides and copper sulfides can include the steps of adding an effective amount of a depressing reagent selected from one ...
Flotation separation of copper-molybdenum... PDF Download Available Chitosan, a natural biodegradable polymer, was studied as a selective depressant in copper-molybdenum sulfide separation by flotation. Although chitosan depressed both molybdenite and chalcopyrite in single mineral flotation, selective flotation was achieved during ...
Effects Of Sodium Alginate On The Flotation Separation Of. In this paper the effect of sodium alginate SA on the flotation separation of molybdenite MoS 2 from chalcopyrite using kerosene as collector was systematically investigated The results of single mineral micro flotation tests indicated that SA exhibited strong depression on chalcopyrite ...
Large Chalcopyrite Magnetic Separator Types Know More. Large Chalcopyrite Magnetic Separator Types 2017-09-22 4 The Separation of Chalcopyrite and Galenite Normally the separation of this type of ore is to get the mixed concentrate of chalcopyrite and galenite at
Chalcopyrite Magnetic Sparation Machine. chalcopyrite roller mill. The electro-magnetic high intensity separators that produce 20 000 gauss the rare earth magnetic separators are relatively inexpensive and can produce magnetic fields around 6 000 gauss To different kinds of mineral ores the application of magnetic separation machine is .
Wet, high-intensity magnetic separation WHIMS was considered as a poten tial method for removing the cobalt-nickel mineral from the chalcopyrite con centrate. In anticipation of such tests, the magnetic susceptibilities were measured on four high-grade mineral specimens--siegenite, chalcopyrite, sphal erite, and galena.
The minerals in the molybdenum ore are molybdenite, pyrite, chalcopyrite , use molybdenum-copper mixed process , pyrite tailings flotation , copper molybdenum separation and partial mixed flotation priority process . Copper molybdenum separation and molybdenum concentrate mainly use sodium sulfide and sodium cyanide process .

Selective Flotation Separation Of Molybdenite And. Dec 20 2019 The flotation separation of molybdenite and chalcopyrite is very difficultly due to their excellent natural floatability Thermally pretreat minerals under 250 C before flotation was investigated as a potential approach for the flotation separation of molybdenite and chalcopyrite ...
The results of this work demonstrate the efficacy of magnetic separation following microwave treatment in the separation of arsenopyrite from molybdenite. AB - The influence of microwave radiation on the magnetic properties of molybdenite and arsenopyrite has been investigated.
magnetic field is dependent in part upon the magnetic susceptibility of the particle. If two minerals of equal vol ume but different susceptibilities are exposed to the same magnetic field and field gradient, the resulting difference in magnetic forces will result in a separation of the par ticles if
From the flotation tailings containing chalcopyrite and galena, copper is recovered by magnetic separation. Desliming has certain influence on the recovery of copper and lead. The magnetic induction intensity of the magnetic medium used in the magnetic separator is 1.2T. The medium was a 6 mm steel ball with a void flow rate of 0.12 ms.
Tailings Magnetic Separator For Molybdenum Ore In Venezuela. The weak magnetic and non magnetic materials can not be attracted and will flow to the discharge pipe for tailings 3 Magnetic seperator application 1 Used for pre concentration in the magnetic separation mill remove the waste stones out of the ore and restore grade 2 Used for stope to recover iron ore from the tailings and increase the
aero 407 promoter for chalcopyrite flotation. aero 407 promoter for chalcopyrite flotation. Flotation Frothers What is the Function of Frothers The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the nonfloatable minerals Frothers accomplish this by lowering the surface tension of the liquid which in ...
Magnetic separation Wolframite has weak magnetic properties, ... Scheelite is often associated with a variety of sulfide ore, common molybdenite, chalcopyrite and pyrite, etc. during the beneficiation process, the sulfide ore should be floated out first.
