A flotation process in which copper ores or copper converter slags are ground and firstly have added thereto benzotriazole or alkyl benzotriazole as an activator and secondly one or more collectors selected from the group consisting of xanthates dithiophosphates thiocarbamate esters dithiocarbamates mercaptans and dixanthogens and further if desired a promoter such as kerosene light oil ...
Abstract. Aiming at the recovery of copper from smelting slag a flotation approach was studied. It was found that this slag composed of fine particles with complex association and distribution in which bornite was the main copper-bearing mineral after a detailed mineralogy analysis via
Abstract: Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings.
Aktogay Copper Mine - Mining Technology. Construction works for the Aktogay copper mine ... It is the largest copper producer in Kazakhstan ... Ore is then processed into slurry by the drive ball mills before being delivered to the flotation section of the ...
And chemicals that facilitate flotation. Compressed air and the flotation chemicals separate the ground slag into various fractions of minerals. Additives cause the copper to float in a foam of air bubbles for subsequent removal dewatering and concentration. Leaching is used to recover copper from slime a byproduct of electrolytic refining ...
Aug 11 2020 Copper is an important nonferrous metal that has been used for thousands of years due to its versatile and highly applicable properties.1 The increasing demand for copper and depletion of high-grade ores have prompted intensive investigation on metal recovery from low-grade ores and secondary copper-bearing resources.2 For low-grade ores or secondary resources such as copper slag
Converter slag Reverbetory furnace slag Copper recovery Flotation Milling and grinding ABSTRACT Namibia Custom Smelters NCS process a range of copper concentrates in their three furnaces namely; top submerged lance copper converter and reverberatory furnaces in order to produce mattes and fayalitic slags. The
Copper is recovered in the Copper Concentrator from chalcopyrite ore converter smelter slag and rotary holding furnace RHF slag via grinding and flotation operations.
Copper recovery. Tailings from flotation of copper slag are a second RCRA special waste. Traditionally reverberatory furnaces have been the most common furnaces used for smelting however they are being replaced by electric or flash furnaces which are more energy efficient. Reverberatroy furnaces also produce large volumes of
Copper Slag Flotation Process Description Flotation process and choosing appropriate reagents recovery of copper is approximately 75 along with copper content in basic copper concentrate of 589 42 leaching analysing the tailing of copper flotation from smelter slag it was noted that there is a significant copper content in it copper.
Copper slag milling and flotation process. copper slag milling and flotation process. Mar 15 2019 Tailings from an industrial copper slag cleaning milling and flotation circuit have been prereduced at low temperatures well below its melting point using CH 4H 2Ar mixtures with the aim of metallizing its iron oxide component to metallic treatment carried out at 700–900 C with a
Correlated the slag mineralogy with flotation performance of copper sulphide. The role of single collectors and collector mixture were evaluated in terms of copper grade and recovery. Examined the flotation results to investigate that whether there was synergistic effect arising from mixing collectors.
Currently the slags are sent to a milling and flotation plant for liberation and recovery of residual copper. The copper recoveries realized in the plant are much lower than expected and it has been postulated that some copper minerals may be occurring in forms that are more difficult to float like oxides or fine disseminations in the gangue ...

Flotation to recover entrained copper contents. This technique produces a flotation concentrate copper ... Copper slag is 2a form of olivine a magnesium iron and silicate mineral with the formula Mg Fe2 2 SiO 4. The production of nano silica from the dissolution of olivine is an economic option when
For an air-cooled slag at optimized conditions 72 of copper was recovered in one stage flotation and a 12.6 copper concentrate was achieved. The best recovery efficiency was obtained when 30 g ...
Jan 01 2009 Copper can be recovered from the slags by froth flotation after cooling crushing and grinding. The obtained Cu-concentrate is sent to the pyrometallurgical process. If grinding is not fine enough for efficient flotation copper is lost in tailings. In this paper the ferric leaching of slag flotation tailings is studied.
Jan 01 2018 In this study the effects of Cu.sup.2 and Fe.sup.3 on the sulphidizing and flotation of copper oxide in copper smelting slag are systematically investigated based on the analysis of chemical composition and phase of copper smelting slag. The interaction mechanism of the Cu.sup.2 and Fe.sup.3 on the copper oxide surface is studied.
Jan 01 2020 Slag cleaning can be divided into two types first being the pyrometallurgical reduction and settling of liquid slag which is performed in slag-cleaning furnaces and the second type being the mineral processing-based slag cleaning of solidified or granulated slag by crushing andor grinding followed by gravity concentration or froth flotation ...
Nov 01 2003 A flotation scheme used at the Almalyk copper smelter for processing slags together with Cu–Mo ores was described and ways to optimise the slag flotation process were examined Sigedin et al. 1986. Results of the flotation of converter slag were presented and the effect of the combined flotation of slags with the ores on the recovery of ...
Nov 30 2008 Copper slag wastes even if treated via processes such as flotation for metal recovery still contain heavy metals with hazardous properties posing environmental risks for disposal. This study reports the potential use of flotation waste of a copper slag FWCS as iron source in the production of Portland cement clinker.

Oct 10 2015 Lowest copper recoveries were obtained with alkyl hydroxamate in single collector floation performance. It has been reported that the alkyl hydroxamate is not very selective for sulphide flotation. In case of copper slag most of the copper occur in the form of copper sulphide and shows very low response with alkyl hydroxamate.
