Copper Recovery from Silicate-Containing Low-Grade Copper

copper ore using flotation followed by atmospheric and high-pressure oxidative leaching. The effects of various flotation parameters, such as flotation time, PAX dosage, slurry pH and air injection rate on beneficiation of copper from the low-grade copper ore were studied. The recovery of copper reached 93.1% and the grade of copper improved to 18.2 mass% from 0.4 mass% under collector-less

RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION

The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching. The ore with 4.21% copper grade used in this study was obtained from Çorum-Dangaz region of Turkey. Native copper, cuprite (Cu 2 O), tenorite (CuO), and malachite (Cu 2 (OH) 2 /CO 3) were the main copper minerals in the test sample. Quartz, calcite

THE EFFECT OF SOLID COMPONENTS ON THE RHEOLOGICAL

paper presents the results of the rheological tests of thickened flotation copper ore tailings as a function of concentration and particle size distribution. The main objective of the experiments was to select the rheological model which will be optimal for the rheological data. The assumptions for building empirical models have been chosen so that they would be simple to use. KEY WORDS

Dynamic froth stability of copper flotation tailings

Flotation tailings, however, usually contain a large proportion of fine (10–50μm)andultrafine (<10μm) material and the effect of these particle sizes on froth stability is not yet fully understood. For this study, samples were obtained from the overflow and underflow streams of the primary hydrocyclone at a concentrator that reprocesses copper flotation tailings. These samples were

Development of copper recovery process from flotation

15/06/2018· The total copper recovered from its ore through flotation process is about 56% [ 6, 18 ], which indicates that the flotation tailings still contain valuable copper components such as chalcopyrite. In addition, old flotation tailings sometimes have a higher copper grade (0.2–0.4%) than that of low‒grade ores (0.2‒0.3%).

Semi-quantitative mineralogical analysis of the flotation tailings revealed significant content of carbonate minerals (approximately 20-25 %), indicating high acid neutralization capacity. Also, approximately 70 % of copper is in the form of the oxide mineral cuprite (Cu 2 O). Copper can be easily leached from cuprite by using sulphuric acid.

The old mine tailings have higher copper grade than that of naturally occurring copper ore (world average: 0.4 %). Due to the lower grade and complex mineralization of copper ore and mine tailings, it becomes difficult to apply the conventional pyrometallurgical method to recover copper from that kind of
