Floatation Machine Copper Ore Wikipidia

Flotation of Copper Ores. In most plants engaged in the flotation of ores containing copper-bearing sulphide minerals with or without pyrite, pine oil is employed as a frother with one of the xanthates or aerofloat reagents or a …

The flotation section consists of two 10-cell "Sub-A" Flotation Machines, one for the lead-copper and the other for the zinc. The launder arrangement and pulp flow is the same for both machines and provides double cleaning of the rougher concentrates. This intricate arrangement of pulp flows is accomplished without the use of pumps and is ...

The copper ore flotation method can be divided into forward flotation and reverse flotation according to the separation of valuable components: discharging useless minerals (gangue minerals) in the slurry as …

In the original polymetallic ore, the Cu content was 0.41 % after subsequent treatment and flotation tests, the Cu content increased to 1.38 % with Cu recovery 86.18 %. Keywords: Copper; Flotation, Polymetallic ore; Potassium amylxanthate (PAX); Zlate Hory 1 INTRODUCTION Separation of minerals from ore is an important industrial process.

The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H2SO4) leaching. The ore with 4.21% copper grade used in this study was ...

The total share of xanthates used in US plants is ~60%, dithiophosphates – about 40%. Suppressors of gangue minerals are not usually used in flotation of copper disseminated ores. But if the pulp has an increased content of slimes, then liquid glass (up to 0.4 g/t) is added to the main copper flotation and to the copper concentrate re-cleaning.

A new method, staged flotation for effectively increasing the recovery of ultra-fine copper oxide ore with a new type of collector (ZH-1, C3-5 carbon chain xanthate) is proposed for the first time. The flotation process and mechanism were examined by flotation tests, entrainment rate analysis, laser particle size experiments and microscopic imagery as well as economic …

1. Crushing and screening: The raw ore is transported to the mine warehouse by the mine car for storage, and then sent to the jaw crusher through the vibration feeding machine for a stage of crushing. The crushed material is transported to the vibrating screen for screening. The screened product is transported back to the fine jaw crusher through the belt for the …

Industrial flotation machines can be divided into four classes: (1) mechanical, (2) pneumatic, (3) froth separation, and (4) column. The mechanical machine is clearly the most common type of …

The cell can be modified to handle high density slurries. RCS flotation technology provides excellent air dispersion, producing fine even sized bubbles. Maximum flotation recovery and performance have been achieved by careful attention to the tank design. RCSTM flotation machines are available in sizes 0,8 m3 to 600 m3 DV™ flotation mechanism

Copper oxide ore has a complex composition, and a low recovery rate is often achieved via the traditional sorting method. A new combined process of flotation–high-gradient magnetic separation–leaching is proposed here to recover copper minerals. The test results showed that the flotation process was successful when using sodium sulfide as a vulcanizing …

The continuous development of the global economy has resulted in a high demand for copper production and high copper consumption [1], [2], and exploitation and effective use of copper oxide mineral resources have attracted attention [3].Copper oxide deposits evolve from shallow copper sulfide deposits after long-term oxidation, and they are widely and abundantly …

Copper content in the ore feed, collector dosage in the rougher and the scavenger flotation circuits, slurry pH in the rougher flotation circuit and frother consumption were selected as input parameters to estimate the copper …

Flotation machine aeration also determines to a certain extent the character of the froth. Finely divided air bubbles thoroughly diffused through the pulp are much more effective …

The present invention provides a kind of copper ore floatation machine stirred tank concentration soft-sensing device and method, including：Turbine flow sensing mechanism, spoke type weighing sensor, imaging sensor, main control module, the power module for powering to measuring system and communication module；Main control module is by communication …

In this study, two new variants of the recurrent neural network (RNN) method were used to predict the copper ore flotation indices, i.e., grade and recovery within different …

Tests made on ore containing $9 gold, 3.5% copper, and 45% insoluble, showed that after crushing to pass 60 mesh and treating by direct flotation, an extraction of 82% of the gold and 96% of the copper could be obtained, with a concentrate containing only 21% insoluble.

Capacity: 0.1-50m³/min per cell. Application: flotation machine is widely used in copper, gold, silver, zinc-lead, nickel, fluorite, antimony ore, molybdenum ore, phosphate ore, lithium, feldspar, fluorite, talc, iron, rutile or other mineral processing plants; It can also be used for separation of ferrous metals and non-metals.

In mineral processing operations, besides target minerals, slurries often contain various metal ions, including common ones with different valence states such as Pb2+, Cu2+, Fe2+, and Fe3+. These metal ions originate from multiple sources during the flotation process, including the dissolution of co-occurring metal minerals during crushing and grinding, the …

Mechanical flotation machines are the most widely used, being characterized by a mechanically driven impeller that agitates the slurry and disperses air into bubbles. ... a 95% recovery of copper in the feed ore might give a concentrate grade of 18% Cu in the total recovered mass, while 80% Cu recovery might give a grade of 25% in the ...

Flotation depends on the fact that the grains of some minerals, and especially of metals, differ in the degree to which their surfaces can be wetted by a suitable solution. The powdered product of grinding the ore is fed into a series of tanks called flotation cells which are filled with a solution containing various oils capable of forming a ...

The Problem with Copper for Porphyry ores and Chalcocite and Chalcopyrite Copper, one of our most important minerals, is found in many parts of the world. One of the major sources of Copper is the so-called porphyry ores such as the large deposits in the west and southwestern United States, Mexico, South America and Europe.. Porphyry ores, with copper …

The proof of lower power-consumption is that the 10 cells of the National Copper Co. were run with a 30-hp. motor and treated 500 tons per day; the same tonnage treated by a propeller machine would have taken close on to 100 hp.

The depression of pyrite in copper ore flotation is a challenge in high salinity water although natural pyrite can be depressed readily at alkaline pH due to the formation of iron hydroxides on pyrite surfaces (Boulton et al., 2001, Mu et al., 2016).In copper ore flotation, a galvanic interaction occurs between copper minerals and pyrite with copper minerals acting as …

The flotation separation process mainly includes: (1) Grind the ore finely by the ball mill or rod mill to dissociate useful minerals from gangue minerals. (2) Separate the ore by the flotation machine. Adjust the ore pulp …

The flotation tests were done using a laboratory Essa flotation machine with a 2.5 L cell. Charges of 1 kg were used in order to obtain a pulp density of 32% solids. The impeller speed was fixed at 800 r/min. The Es of the slurry was controlled with a silver/sulphide combination electrode. Grab samples of flotation feed and final tails were ...

The separation efficiency of flotation copper is 85.45%, indicating that this copper sulfide ore can be effectively recovered using this separation process. In addition, the grades of associated precious metals in the concentrate were 0.740 g/t Au and 42.90 g/t Ag, with respective recoveries of 9.22% and 26.66%, indicating that these metals ...
