The flotation target was a higher nickel recovery from a concentration grade of 4 nickel and 35 iron. Sulphide ore is mainly associated with the following minerals pyrrhotite, pentlandite, chalcopyrite and pyrite. Pentlandite is the most abundant sulphide mineral and is the main nickel mineral in almost all nickel sulphide deposits 4, 5, 6.
Apr 01, 2019 Flotation of low grade nickel sulfide ores into a concentrate suitable for smelting, and at acceptable nickel recovery, can be challenging. Alteration of the gangue minerals can mean talc is present in considerable quantities. Talc floats naturally and can be very difficult to depress without significant nickel losses. High talc bearing ores have often been considered untreatable.
Case Study Savannah Mine Nickel Flotation With Pyrrhotite Gangue. We tested a nickel sulfide ore from the Savannah mine with an on-site laboratory flotation cell. The standard flotation reagent suite was compared with the addition of 300 gpt of Pionera F-300 and an additional aeration step in a rougher flotation setting.
16.1 ORE TYPES AND MINERALOGY. There are more than 45 different nickel minerals, but only a few are of economic importance. Table 16.1 lists some of the most important nickel minerals. Nickel, in various ores can also be found in other minerals, such as pyrrhotite and various cobalt minerals as an exsolution in isomorphic phases.
SNF Flomin C products are widely used for the flotation of Xanthates provide a wide range of collection power, copper, lead, zinc, gold, nickel, platinum group elements enabling the flotation metallurgist to cope with practically and others. Although the base line of products consists of any problem involving sulfide minerals. However, the best
The use of a reagent selected mode when the specified proportions provided high level target recovery of base metals and PGMs in bulk concentrate even from the flotation pulp with low solid content Nickel - 71,28, copper - 82,72, IPY 71,05.
Flotation of cobalt sulfide ores can be best achieved at acidic pH . 4 with xanthate collectors and at pH of about 7.5 for oxide ores with nitrosonaphthol chelating reagents, while their ...
Mar 25, 2019 The aerosol method is a new preparation method that enhances the effect of flotation reagents. The essence of this method is to use a special spray device to directly add the flotation reagent to the flotation cell after the flotation reagent is atomized in the air medium, so this method is also called aerosol flotation method.
A method for the flotation of nickel and copper sulphide minerals from talcose bearing ores using an alkaline circuit in which at least one of the alkaline reagents is soda ash or ammonium hydroxide and following conditioning of the pulp with a collecting agent of the xanthate family to activate the nickel and copper sulphide materials, the pulp is conditioned with a flocculating agent to ...

A process in which manganese is recovered from manganese nodules after the nodules have been treated to recover base metals such as copper, nickel, cobalt, and molybdenum. The process includes the steps of reacting the manganese in the nodules to yield a carbonate and subjecting the manganese carbonate to flotation. The manganese carbonate froth is collected from the top of a flotation cell ...

A new depressant for use in enhanced separation of polymetallic sulphides is described. The depressant agent is used in conjunction with conventional collector agents and frothing agents in the flotation separation of copper, nickel, lead, zinc sulphides by depressing iron sulphides such as pyrrhotite, pyrite and marcasite in the tailing.
2016-6-10 The challenges in processing nickel laterite ores using flotation process were comprehensively reviewed. Literature shows that flotation has not been successful to recover nickel from laterite ores. Nickel in laterite ores is often finely disseminated in various minerals in very fine size.
The truth is, high-grade nickel reserves are being readily depleted, and mining companies are looking for new ways to recover nickel, this highly desired base metal. Id like to dig a little deeper into the recovery of nickel, specifically from low-grade ores in the Earth,

The reaction of excess CdSiF glyme glyme dimethoxyethane with trimethylphosphine metal dibromides of platinum, palladium, and nickel yielded the trifluorosilyl substituted dialkyl compounds -PtSiFPMe, PdSiFPMe, and NiSiFPMe.
The nickel silicates are treated using either pyrometallurgical or hydrometallurgical methods. The reagent practice in the flotation of nickel and coppernickel ores depends on three basic factors mineralogy of the ore, flowsheet employed in the treatment of a specific ore, and degree of liberation.
