Abstract: There are abundant diasporic bauxite resource in China. The gravity separation and flotation process are utilized for treating this kind of ore. When the ore grinding fineness is -200 mesh 80%, the qualified bauxite concentrate can be obtained, and it contains Al 2O3 71.62%, SiO 2 8.94%, and its Al 2O3 recovery rate is 75.43%, A/S is 8.02.Compared with single flotation process, it can be reduced for the dosage flotation reagent and the cost of mineral processing. Introduction China's bauxite resources are rich, the amount of resources of 1.914 billion, ranking the fifth in the world, but more than 80% are medium and low grade ore, Aluminum silicon ratio (A/S) between 4 to 7 of the bauxite accounted for 59.5%. These minerals can not meet the basic conditions for the production of alumina by Bayer process. (A/S>8) [1]. The vast majority of China's bauxite belong to high-alumina, high-silicon, fine-grained embedded diaspore-type bauxite, so the bauxite is difficult to concentrate.

INTRODUCTION The generation of industrial solid waste constitutes an environmental problem that requires efforts for adequate disposal. Currently, in Brazil, solid waste management is standardized, with a classification determining the management according to its hazardous characteristics. ABNT NBR 10004 is a Brazilian Standard to solid waste and classifies its as: Class I (hazardous), Class II - A (non - hazardous and non - inert) and Class II - B (non - hazardous and inert) according to the concentration of elements that have potential risks to the environment and public health (ABNT NBR 10,004, 2004) A process with a large generation of wastes is the production of copper. Several studies in the last decades investigated routes to recovery copper and other metals of interest from the slag (solid waste from the foundry). In the case of primary production, the slag has copper contents between 0.5 and 2% and the volume generated is twice the refined metal (Schlesinger et al., 2011) In addition to primary copper production, there is a significant rate of the copper production from scrap/waste metal. Secondary copper production in Brazil in 2014 reached 23,600 tons, representing around 9% of domestic production.

Two procedures were employed and compared, the acid hydrolysis method and direct (aquo) hydrolysis. The CN– ion released was reacted with Na+ via ion exchange to replace the hydroxyl ion (OH–) and yielded NaCN. The NaCN was crystallized via evaporation in an air ventilated oven by maintaining the temperature of the reaction solution at 100oC. The crystalized salt was quantified using the modified Vogel’s Argentometric method of cyanide quantification. The concentrations were found to be 10.56 mg/g for whole tuber, 13.92 mg/g for tuber tissue and 4.5 mg/g for cassava peels. Analyte grade sodium cyanide purchased off shelf was used as a reference. The crystals were characterized using, X-ray diffraction analysis; the X-ray diffractogram confirmed the products from acid hydrolysis was a cyanogen (CN2CN2) while the product from direct hydrolysis was sodium cyanide.

Extraction of Copper at Elevated Feed Concentrations R.E
SGS MINERALS SERVICES TECHNICAL PAPER 2003-07 2003 EXTRACTION OF COPPER AT ELEVATED FEED CONCENTRATIONS R.E. MOLNAR, N. VERBAAN –– SGS ABSTRACT A number of flowsheets have been designed and operated, or are currently being considered, to extract copper from leach solutions having much more copper than the 4 g/L levels typically found in heap leach liquors. Dealing with these solutions has required that the envelope for “normal” copper solvent extraction be pushed beyond the usually considered limits. Others have published information on flowsheets to recover copper from leach liquors containing over 25 g/L copper. Secondary solvent extraction circuits are often required to attain satisfactory overall recoveries. This paper reviews some of the issues faced in three pilot plant circuits that were operated by SGS Lakefield Research to produce cathode copper from solutions containing 8 to 20 g/L Cu. The primary objective was to maximize copper extraction using one solvent extraction circuit. The role of feed acidity and the disposition of impurities such as iron and chloride are considered. The challenges of running short SX piloting campaigns are discussed. INTRODUCTION In more recent years hydrometallurgy is finding wider application in the treatment of complex ores that contain copper. Very often, the plant will need to process a Copper solvent extraction was originally sulphide concentrate rather than an oxidised copper ore that is readily leached at developed in the 1960’s to recover ambient conditions. It is probably going to be using more aggressive oxidative leaching copper from relatively dilute leach methods, for example, oxygen pressure leaching. Higher percent solids are employed solutions, typically heap leach liquors in the leaching stages both to keep plant sizes as small as practically possible, and to with copper tenors in the 1 to 4 g/L ensure that the heating requirements of the process are being fully met by oxidising range.

Copper Hydrometallurgy and Extraction from Chloride Media
COPPER HYDROMETALLURGY AND EXTRACTION FROM CHLORIDE MEDIA JAN SZYMANOWSKI SK96K0015 Institute of Chemical Technology and Engineering, Poznan University of Technology, PI. Sktodowskiej-Curie 2, 60-965 Poznan, Poland The development of copper hydrometallurgy is presented and various processes proposed for copper recovery from sulphide concentrates are discussed. Leaching, extraction and stripping are considered, including reagents and processes. The extraction of copper from chloride solutions is discussed. Various extractants are presented and their use for copper transfer from chloride solutions to the organic phase and back to chloride and to sulphate solutions is discussed. Hydrometallurgy is used for copper recovery for more than 300 years. Already in 1670 the mine waters were treated with iron to precipitate copper. However, two hundred years were needed to process oxide ores by vat leaching and copper cementation with iron. The development most important to copper hydrometallurgy, both with respect to the growing number of its applications and for its future potential, has been solvent extraction (SX). 1 It started in 1968 in a small scale and in about 1974 in a large scale of about 100 000 tones/year copper. These operations have served as a stimulus for at least of 30 copper plants, recovering nearly 800 000 tonnes/year of copper with the application continuing to increase. New processes are now developed to recover copper from sulphide ores and concentrates, including CLEAR Process and CUPREX Process. Chloride-based processes play a key role in the metallurgical and chemical industries. 2 One of the most important factors responsible for the significant role of chloro-based processes is the ease of chlorine recycling.

Leaching of Lead and Copper by Citric Acid from Direct-To-Blister Copper Flash Smelting Slag
Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 8 November 2018 doi:10.20944/preprints201811.0209.v1 Leaching of Lead and Copper by Citric Acid from Direct-to-Blister Copper Flash Smelting Slag Krzysztof Gargul, Piotr Jarosz, Stanisław Małecki AGH University of Science and Technology, Faculty of Non-ferrous Metals, al. Mickiewicza 30, 30-059 Kraków Correspondence: [email protected]; Tel.: +48 12 617 2646 Abstract: Direct-to-blister copper flash smelting slag contains up to 14% of copper and 2-4% of lead. Considering this fact, this material is subjected to the high-temperature reduction process. After this, converting process is performed on the Cu-Pb-Fe alloy being the product of decopperization process in electric furnace. An alternative to the presently used processing of flash smelting slag would be its hydrometallurgical treatment and selective recovery of Pb and Cu. This paper presents the results of laboratory tests on flash smelting slag leaching with citric acid solutions. The experiments performed allowed to determine the process parameters at which the Pb concentration in the post-leaching sediment reached the value of 0.41-0.6% while the Pb content in flash smelting slag was 3.05%. Analogous values for copper were 11.5-11.8% (after leaching) and 12.44% (before). Material after leaching in citric acid solutions can be processed, in the second step, using sulfuric acid solutions, and it could lead to the recovery of almost all copper contained in it. Keywords: blister copper, flash smelting slag, citric acid, lead recovery, leaching 1. Introduction As a result of melting of copper concentrates in direct-to-blister flash smelting furnace, a slag with a significant copper content (12-16%) is obtained as one of the products.

Iron Recovery from Bauxite Tailings Red Mud by Thermal Reduction with Blast Furnace Sludge
applied sciences Article Iron Recovery from Bauxite Tailings Red Mud by Thermal Reduction with Blast Furnace Sludge Davide Mombelli * , Silvia Barella , Andrea Gruttadauria and Carlo Mapelli Dipartimento di Meccanica, Politecnico di Milano, via La Masa 1, Milano 20156, Italy; [email protected] (S.B.); [email protected] (A.G.); [email protected] (C.M.) * Correspondence: [email protected]; Tel.: +39-02-2399-8660 Received: 26 September 2019; Accepted: 9 November 2019; Published: 15 November 2019 Abstract: More than 100 million tons of red mud were produced annually in the world over the short time range from 2011 to 2018. Red mud represents one of the metallurgical by-products more difficult to dispose of due to the high alkalinity (pH 10–13) and storage techniques issues. Up to now, economically viable commercial processes for the recovery and the reuse of these waste were not available. Due to the high content of iron oxide (30–60% wt.) red mud ranks as a potential raw material for the production of iron through a direct route. In this work, a novel process at the laboratory scale to produce iron sponge ( 1300 C) or cast iron (> 1300 C) using blast furnace ≤ ◦ ◦ sludge as a reducing agent is presented. Red mud-reducing agent mixes were reduced in a muffle furnace at 1200, 1300, and 1500 ◦C for 15 min. Pure graphite and blast furnace sludges were used as reducing agents with different equivalent carbon concentrations. The results confirmed the blast furnace sludge as a suitable reducing agent to recover the iron fraction contained in the red mud.
