The impact of water quality on flotation performance SAIMM
water quality in minerals separation processing. Whilst consideration of pulp chemistry has encompassed solution assays and species affecting pH, Eh and some precipi tation, a systematic and comprehensive approach to modelling the behaviour of solution species integrated with their effect on mineral surfaces is not normally undertaken.
Minerals Special Issue Flotation Chemistry
Sedimentation and flotation tests reveal that conditioning can effectively remove chlorite slimes from pyrrhotite surfaces, resulting in an enhanced flotation recovery of pyrrhotite. When mixed minerals were conditioned under the natural atmosphere, a faster conditioning speed and longer conditioning time decreased the flotation recovery of pyrrhotite.
Copper Recovery from Barren Cyanide Solution by Using
of copper minerals including copper oxides, carbonates, suldes (with the exception of chalcopyrite) and native copper are highly soluble in cyanide solutions [2]. These copper containing minerals are problematic because, when ores containing such minerals are leached with cyanide to recover the gold, copper also dissolves to
v116n6a16 Selenium minerals and the recovery of selenium
selenium minerals, as well as the recovery of selenium from copper refinery anode slimes. Our focus is on the occurrence of selenium minerals and selenium deposits. We also examined the research work reported in the literature on the treatment of copper refinery anode slimes for the recovery of selenium. 91967/007693812

How to Recover Copper Precious Metals in Electronic Scrap
A recovery of 99.6 pct of the copper was obtained from the head solution with a utilization of 69.7 pct of the scrap added. A similar test made on minus 10 mesh scrap, also shown in table 4, indicates substantially lower copper recovery and scrap utilization than the minus 35 mesh material.

In situ leach
In situ leaching (ISL), also called in situ recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ. In situ leach works by artificially dissolving minerals occurring naturally in a solid state.

leaching was investigated with respect to acid concentration and solid to liquid ratio. The copper concentration in the leach solution ranged from 0.80 to 1.75 g dm 3. The total Cu recovery rate ranged from 30 to 56 %, whereas the recovery rate of copper oxide minerals ranged from 67 to 100 %. Furthermore, with increasing the amount of liquid

AN INVESTIGATION OF COPPER RECOVERY FROM A
The copper recovery, malachite recovery, minor copper recovery and copper grade responses were optimized using JMP statistical software. Indicators of model inadequacies were noted but since the models predicted sensible solutions, inaccurate test ratios and un modeled effects were hypothesized to be the source of the inadequacies.

Introduction to Mineral Processing Chevron Phillips Chemical
This material is referred to as pregnant leach solution. Oxide copper minerals are very soluble in the leach solution. Sulfide minerals are rendered soluble by certain bacteria that feed on the sulfide minerals and convert them to soluble sulfates and other soluble forms. This biological action tends to maintain the acidity of the leach solution.
Copper recovery using leach/solvent extraction
sulphuric acid leach solutions4. Generally Mills had already developed and commercialized Alamine 336 as an SX reagent for the recovery of uranium from sulphuric acid leach liquors5 and believed that a similar technology for copper recovery would be welcome. However, an extensive market survey showed that the industry reception for copper recovery

THE COPPER AGETHE BRONZE AGETHE MIDDLE AGES AND LATERMININGALSO IN THIS ISSUEPre dynastic Egyptians knew copper very well. In hieroglyphic writing the symbol used to denote eternal life, the ankh, was also used to represent copper. The Greek philosophers later adopted the symbol, slightly modified, as . The connection between eternal durability and the lifetime cost effectiveness of copper and its alloys is surely not coincidentalThe Egyptians obtained most of their copper from the Red Sea Hills, but copper predates ancient Egypt by several millennia, and it is now k

Innovations Introduction to Copper Mining Extraction
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
