A New Application For Flotation Of Oxidized Copper Ore

2013-12-24  The Flotation of Oxidized Copper Ore: This study was carried out under the conditions indicated in table 1. Flotation timewas 3 minutes. In the first test with a run of mine ore sample, it was determined that theconcentrate (copper and cobalt) obtained from this study was 5.07 g while the tailing was92.53 g. In untreated samples, 14.90 % of the copper and 4.40 % of the cobalt reported tothe concentrate phase, which are not acceptable concentrations. In the second series oftests, oxidized copper ore

A test of a slow floating platinum ore, for instance, may require 45 minutes to an hour to reach completion and thus the first concentrate can be collected after two minutes of flotation. A faster floating copper porphyry flotation test, however, may finish in five minutes and a first

RECOVERY OF COPPER FROM OXIDE COPPER ORE BY

2014-12-24  Results of flotation tests were unsuccessful in terms of both recovery and grade of concentrate product. The highest copper recovery of concentrate was found as 61.35% with 8.69% copper content. The concentrate with highest copper grade of 34.65% was obtained with only 26.98% copper recovery. Unsuccessful flotation of the test sample was due to unfavorable morphologic properties of native copper

If only assays are available, the ratio of concentration equals (20 0.1)/(2.09 0.1) = 10

A Comparative Study of Kinetics of Flotation of a Copper

2012-11-30  Copper-nickel ore from INCO mines, Sudbury, Ontario, Canada was used in the experiments. The approximate ore composition was pentlandite 4-5%, chalcopyrite 4-5% and pyrrhotite 30-35%. The ore was ground in a polyurethane lined rod mill with stainless steel charge to avoid any external iron getting into the flotation system.

Behavior of talc and mica in copper ore flotation

2018-8-1  Tests were conducted on slurries comprising the copper ore and varying concentrations of talc and muscovite. The flotation tests were conducted at 32 wt% slurry (as it is common in flotation work). The overall slurry wt% was kept constant despite the increasing addition of talc and muscovite in order to avoid the effects of slurry wt% on the rheology.

AN INVESTIGATION OF COPPER RECOVERY FROM A

2010-1-19  The flotation of a natural porphyry copper ore with bornite and malachite was investigated via fundamental work with pure minerals and a bench-scale testing regime. The processing of the test ore was problematic due to a mineral assemblage that caused prevalent slime generation.

Froth Flotation an overview ScienceDirect Topics

Copper (or metal) recovery percentages of the flotation circuits of a copper mine/mill are extremely important. For example, it is estimated that for a plant processing 50,000 tonnes of ore containing 1% copper per day, increasing the copper recovery from 86 to 87% of that contained in the ore could increase revenues by approximately $4 million
