Total Mining Solutions is the umbrella name under which Total offers our mining customers a range of products and services designed to optimize their hydrocarbon management while at the same time reducing their costs.
From the copper mines of Chile to mining sites across the world, we have developed global expertise for choosing the right fluid to effectively extract valuable metals. Escaid hydrocarbon diluents are used as diluents for the solvent extraction of minerals including copper, nickel, cobalt, uranium and zinc.
Extraction efficiency An independent RD program consisted in comparing the copper over iron selectivity using Elixore aliphatic diluents and conventional aromatic diluent in the same solvent formulation (extractant + diluent).
extraction, many papers were published that not only did not recognize the effects of diluent on solvent extraction circuits but failed to identify the diluent in use. Since the diluent makes up over 900/0 of the circuit organic in many plants, this materiaJlogicaJly should be expected to exen a strong influence on the behavior of the circuit.
Total offers ELIXORE, a range of high purity diluents to optimize extraction efficiency and cost. Where to use metal extraction diluents? After the metal ores have been pre treated and crushed, they can be refined to a high level of purity and concentration by hydrometallurgy, a process which uses Special Fluids ELIXORE metal extraction diluents.
desirable diluent is needed. Orfom174; SX 12 Solvent Extraction Diluent has been specially treated to minimize problems associated with copper cathode removal and optimize phase break times. This product is the preferred product for superior phase disengagement and rapid transfer kinetics in solvent extraction circuits.
Solvent Extraction Diluents. The discussion to this point has been centered around the reagents used for metal extraction, yet, in many commercial SX plants the diluent used as a carrier for both the reagent and the reagent metal complexes is present in far larger amounts than the reagent.
Diluent properties that favor interaction between the extractant and the diluent result in lower metal extraction rates. The nature of interaction between the extractant and both aromatic and aliphatic diluents may be described in terms of physical parameters. The choice of the diluent is shown to affect the rate of metal extraction.
The effect of different types of diluents on the extraction of neodymium(III) from a chloride aqueous feed solution by the acidic extractant bis(2 ethylhexylphosphoric) acid (D2EHPA) was investigated. A total of 11 aliphatic, mixed aliphatic aromatic and aromatic diluents were considered.
Shell global business development manager Monica Karamagi explains that diluents play a critical role in the extraction of copper, uranium, nickel, cobalt, zinc and other metals.
elixore diluent for metal extraction Aliphatic diluents for metal extraction To ensure optimal performance in terms of operator safety, process efficiency and reliability, TOTAL has designed the ELIXORE range, perfectly defined aliphatic diluents dedicated to liquid to liquid extraction processes.
The effect of diluents on the rate of extraction of copper using di 2 ethylhexylphosphoric acid and 5 nonylsalixylaldoxime as extractants has been explored.
It is known that the diluent does not act merely as a carrier but also participates in the extraction process since rates of metal extraction can often be related to the diluent and the modifier selection 3 6 Ritcey, G.M. and Lucas, B.H. 1974.
(PDT), copper extraction kinetics and extraction reagentcopper complex solubility was evaluated as a function of diluent source, reagent type and temperature. For all SX experiments the reagent concentration was made up to 38% (v/v) in the desired diluent.
The influence of diluents on extraction properties has been investigated. The extractants used are Lix984(Henkel) and M5640(Zeneca), and the adaptability of this diluents to these extractants is compared. The checked extraction properties include loading capacity, extraction and strip kinetics, copper/iron selectivity and phase disengagement. The results showed that DSR3 is a suitable diluent

Global portfolio High performance diluents Extraction diluents for today and tomorrow They are used extensively in the extraction of copper, nickel, uranium and other valuable metals. In fact, they are relied upon in some of the worlds largest mining operations.
Extraction isotherm for copper indicates that a total of four stages are required for complete extraction of copper whereas, complete extraction of zinc could be achieved in three stages using the phase ratio of 1.11 and 1.91 respectively (Figure 5 and Figure 6).
Liquidliquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.

diluent source and extraction reagent. Finally, SX performance, including phase disengagement time (PDT), copper extraction kinetics and extraction reagentcopper complex solubility was evaluated as a function of diluent source, reagent type and temperature.
The stripping of copper from the organic phase was also studied. For an initial copper concentration of 1.5 g dm 3 extraction efficiency decreases as the concentration of tetralin increases in the diluent mixtures of dekalin tetralin.
Extraction Efficiency based on good selectivity. An independent RD program compared copper over iron copper over iron selectivity by using Elixore and classical aromatic diluents in the same solvent formulation (extractant + diluent). Extraction efficiency of ELIXORE compared to aromatic diluents.
Monica Karamagi There are different types of mining diluents. The goal of the solvents extraction processes is to maximize your yield of copper ore thats coming out of the metal.
on percent extraction of copper and nickel for organic to aqueous (OA) phase ratio of 21 at pH 2. Experimental results showed that at pH 2, copper was selectively extracted from its mixture with nickel. Selectivity for copper extraction was as high as 6000 with 40% LIX 664N.
International Copper Study Group estimates that solvent extraction electrowinning (SX EW) production of copper is expected to increase by 4.4% annually to reach 5.2 Tg
diluents used for copper(II) extraction is their low extraction capacity (maximum copper concentration to obtain in loaded organic phase), which reaches from 6 to 8 g Cu(II)/dm3 (Szymanowski, 1990). According to Eq. 1, the extraction reaction of metal cations is reversible towards hydrogen ions. Equilibrium state of the reaction (Eq.
The copper bearing aqueous phase is advanced to the electrowinning (EW) stage of the process while the barren organic phase is returned to the extraction stage of the process. In the electrowinning stage of the process the copper is reduced electrochemically from copper sulfate in solution to a metallic copper cathode.
percolates through the stockpile dissolving copper minerals, producing a copper laden liquid called pregnant leach solution (PLS). The PLS flows to a collection reservoir, and then to a solvent extraction plant where it is mixed with a diluent designed to extract the copper. The leach solution minus its copper
