The purpose of this paper is to study metal separation from a sample composed of a mixture of the main types of spent household batteries, using a hydrometallurgical route, evaluating the parameters effect of the liquidliquid extraction, with Cyanex 272, and stripping. The preparation of solution consisted of: grinding the waste of mixed batteries, reduction and volatile metals elimination using electric furnace and acid leaching. With the best results obtained after liquidliquid extraction and stripping it was possible to get 4 solutions of metal sulfates that they could be used in posterior metals recovery by electroplating, they are: 1) to copper recovery: Cu 203.7 g L-1+ Co 20.8 g L-1+ Mn 2,626.6 g L-1; 2) to cobalt recovery: Co 364.0 g L-1; to manganese recovery: Mn 49,929.0 g L-1and 4) to nickel recovery: Ni 1,241.9 g L-1.

Bench-scale experiments were conducted to recover lanthanum and cerium from Indian red mud in a hydrochloric acid medium. The method includes acid leaching of red mud pulp and subsequent liquid-liquid extraction of the leached metals with different organic extractants, in order to establish the technical feasibility of extraction and separation simultaneously. The maximum extraction of 88.5% La was achieved at 95 °C, using 1 M HCl, S/L ratio = 1/100 in 1 h with 200 rpm agitation rate. At this temperature, cerium recovery (99.9%) was found to be maximum. The maximum recovery of cerium (99.9%) can be achieved even at 55 °C, while the recovery of lanthanum lowered to 78.5% under same conditions. Liquid-liquid extraction of leached metals was tested to be complete and selective using Cyanex 923, as against Cyanex 301 and Cyanex 272.

Liquid Liquid Extraction

This work presented data using always real solutions yielded from the treatment of Spanish raw material, in detail, from a slag obtained in a pyrometallurgy process of tin production from mining tailings containing mainly cassiterite and columbo tantalite. In this investigation the raw material was treated by acid leaching, using HF/H2SO4 as a leaching agent. Then, liquid-liquid extraction of Nb and Ta have performed with Cyanex®923 extractant, further, both metals were separately stripped. Once metals were separated into two aqueous solutions, they were precipitated and calcined to yield the corresponding compounds (Nb2O5 of 98.5% purity and Ta2O5 of 97.3% purity).

Countercurrent Process

The aim of this paper was to propose and test a continuous cobalt recovery process from waste mobile phone batteries. The procedure started with dismantling, crushing, and classifying the materials. A study on leaching with sulfuric acid and hydrogen peroxide was carried out with subsequent selective separation of cobalt by means of liquid–liquid extraction. The best extraction conditions were determined based on a sequence of experiments that consisted of selecting the best extractant for cobalt, then assessing the impact of extractant concentration, pH, and contact time on the extraction yield. With these conditions, an extraction isotherm was obtained and correlated with a mathematical model to define the number of extraction stages for a countercurrent process using the McCabe–Thiele method. Then, a similar study was done for stripping conditions and, as a last step, cobalt electroplating was performed. The proposed process offers a solution for the treatment of these batteries, avoiding potential problems of contamination and risk for living beings, as well as offering an opportunity to recover valuable metal.
