A comparison of results for flotation of a copper ore (4% bornite) ground in rubber-lined and un-lined mills with stainless and carbon steel rods and balls indicated that the best copper recovery was achieved when the rubber-lined mill and stainless steel media were used.
In the field of mineral processing, the successful flotation of target minerals requires sufficient liberation through grinding. The aim of this paper is to compare and evaluate the performance of ball versus short cylindrical media for comminution of dolomite by point and line contact, respectively. The results of the grinding experiments indicate …
Copper grade in concentrate (E), copper grade in tailings (- ), and copper recov- ery in a concentrate (H) were selected as factors for the evaluation of the flotation per- formance (performance indicators).
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 froth. Air is pumped into each cell, the solution being …
It started with copper flotation tests in fresh water to identify the lowest recovery of pyrite that could be achieved, followed by copper flotation tests in high salinity water with pyrite depressed by the combined use of MBS and Hi-Cr steel grinding media.
Copper alloy C110, also known as electrolytic tough pitch (ETP) copper, is a widely utilized and commercially important grade of copper alloy. Renowned for its exceptional …
Selectivity and power of frothers in copper ore flotation 517 The ore was crushed in a jaw crusher to obtain particles smaller than 1 mm in size. Prior to each flotation experiment, the crushed material was wet ground in a steel ball mill. The size distribution of the ore, used as the flotation feed, is presented in Table 1. Table 1.
As one of the purest copper on the market, C110 copper also has the highest thermal and electrical conductivity values. Oxygen content is restricted to maximise hydrogen …
Given these controlled-potential flotation techniques had proved beneficial in the selective flotation of enargite from other sulphide copper minerals in the Tampkan ore, it was deemed worthwhile to determine whether the same methods would also be applicable to the selective flotation of tennantite from Northparkes ore.
The present study explores the potential of 2-(4,4-dimethylpentan-2-yl)-5,7,7-trimethyloctanoic acid (2-DMPT) as a collector for the reverse flotation of smithsonite from dolomite. Micro-flotation ...
This paper reviews the literature on the recovery of the above mentioned minerals by flotation. The increasing complexity of ore deposits, declining ore grades and higher global demand for copper ...
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 froth. Air is pumped into each cell, the solution being agitated to bring froth of bubbles to the surface.

A better solution may be to use a specially-designed flotation cell known tentatively as second-order flotation (SOF) cell. In this process, microbubbles are …
As part of a study investigating the influence of mineralogical variability in a sediment hosted copper–cobalt deposit in the Democratic Republic of Congo on flotation performance, the flotation of nine sulphide ore samples was investigated through laboratory batch kinetics tests and quantitative mineral analyses. Using a range of ore …
Each flotation feed consisted of dolomite, quartz and one of following components: chalcopyrite, chalcocite, ... worse than those with standard copper ore flotation such as xanthates (Drzymala et ...

In most copper sulphide flotation processes, optimising recovery of trace elements such as gold or maximising the rejection of penalty elements such as uranium, arsenic and fluorine remains a major metallurgical challenge.
Three factors were measured in the flotation process of copper ore: the copper grade in a concentrate (β), the copper grade in tailings (ϑ), and the recovery of copper in a …
To maximize the yield of copper, pH control is necessary in the flotation tanks. Process. Crushed ore (containing 1 to 2 % copper), along with water and a lime slurry, is fed into …
Looking for copper minerals flotation, Hassanzadeh (2016) reported a study on the effect of the distribution of chemical reagents on copper grade and recovery in industrial rougher flotation cells
This document summarizes the development of large flotation cells used in copper processing. It discusses how cell sizes have increased from 160 cubic meters in the past to the current largest size of 660 cubic meters. It also notes that while the basic operating principles of flotation cells have remained the same, developing technologies that …
BRYAN METALS INC. 4801 Olympia Park Plaza, Suite 3500 Louisville, KY 40241 Ph: 502-873-3000
For some time past the company has been experimenting with a view to finding the best method of concentrating the sulphide ore before smelting. The first test-mill consisted of two sets of rolls, one Chilean mill, one Hardinge conical mill 6 ft. diam. by 12 in. cylinder, Richards hindered-settling classifier, Deister tables, some kind of ...
The present work investigates a comparative study between mechanical and ImhoflotTM cells on a mini-pilot scale and the applicability of one self-aspirated H-16 cell (hybrid ImhoflotTM cell) on an industrial scale on-site. The VM-04 cell (vertical feed to the separator vessel with 400 mm diameter) was fabricated, developed, and examined. The …
Following the grinding process, the ore underwent flotation in a 3 L modified Denver cell at 1200 rpm rotor speed. This modified flotation cell was equipped with an impeller driven from below to ensure consistent froth scraping.
