    <p>The scope of this study was to improve the hydrometallurgical processes involving iodine-iodide leaching and precipitation for recovery of gold from waste printed circuit boards. Firstly, the influence of different precipitating agents, namely ascorbic acid, trisodium citrate and sodium hydroxide on the recovery of gold from gold-iodide leach liquor were investigated in order to define the most effective precipitating agent. The leach liquor was prepared by dissolving pure gold chips in 1:6 molar ratio of iodine-iodide solution at 40°C, 550 rpm for 12 h. The variables, which affect the efficiency of gold precipitation from the leach liquor, were the molar ratio of precipitating agents to gold, pH and redox potential of the solutions. The attained high gold precipitation efficiency from the leach liquor was more than 99% under the highly acidic (pH < 1.6) and alkaline conditions (pH > 13) induced by 0.1 M ascorbic acid and 0.1 M sodium hydroxide respectively, but 64.5% of gold at a weak alkaline condition (pH 8) with 0.1 M trisodium citrate. Secondly, physico-chemical properties of resultant colloidal solutions and prepared gold particles were examined. Finally, recycling of waste printed circuit boards (WPCBs) via iodine-iodide leaching followed by the ascorbic acid reduction was discussed. Results indicate that over 95% of gold extracted from WPCBs by two-step iodine-iodide leaching under the defined conditions, while the dissolution efficiencies of other precious metals (Ag, Pd) and metal impurities (Cu, Al, Fe, Ni, Pb and Zn) were less than 1% and 3%, respectively. The vast majority of Au (99.8%), Cu (95.6%) and Ag (76.8%) were precipitated from the pregnant leach solution by ascorbic acid reduction at ambient conditions.</p>

  • Volatilization of Arsenic and Antimony from Tennantite/Tetrahedrite Ore by a Roasting Process

    <p>The volatilization of arsenic (As) and antimony (Sb) impurities in a copper ore consisting of tennantite (Cu<sub>12</sub>As<sub>4</sub>S<sub>13</sub>)/tetrahedrite (Cu<sub>12</sub>Sb<sub>4</sub>S<sub>13</sub>) by roasting in both nitrogen and air atmospheres was investigated in this study. The roasting experiments were performed at different temperatures ranging from 500 to 1200°C and different retention times from 15 to 60 minutes while the nitrogen and air flow to a furnace chamber was same as 300 ml/min.</p><p>The results showed that at 700°C, the maximum As volatilization in nitrogen and air atmospheres was reached over 90% and about 70%, respectively. Whereas the maximum Sb volatilization was about 90% at 1200°C in a nitrogen atmosphere and over 95% at 600°C in an air atmosphere. Meanwhile, copper and iron in the ore sample were not volatilized under the conditions. The contents of As, Sb and Cu in the residue obtained from roasting at 1200°C in a nitrogen atmosphere were 0.004 mass%, 0.75 mass% and 34.2 mass%, while their contents were 0.45 mass% As, 4.19 mass% Sb and 34.5 mass% Cu in the residue from roasting at 1000°C in an air atmosphere. Volatilization of arsenic from enargite, arsenic and antimony from tennantite/tetrahedrite sample containing chalcopyrite in a nitrogen atmosphere under the determined roasting condition were also discussed.</p><p>It suggests that As and Sb can be selectively separated from each other/other metals by volatilization. On the other hands, high grade copper concentrate with lower As and Sb contents can be made by volatilization in a nitrogen atmosphere.</p>

    <p>In this paper, we present the results for recovery of copper from silicate-containing low-grade copper ore using flotation followed by atmospheric and high-pressure oxidative leaching. The effects of various flotation parameters, such as flotation time, PAX dosage, slurry pH and air injection rate on beneficiation of copper from the low-grade copper ore were studied. The recovery of copper reached 93.1% and the grade of copper improved to 18.2 mass% from 0.4 mass% under collector-less optimum flotation conditions. The enrichment ratio of copper in the concentrate was 45. The copper concentrate obtained from flotation of the low-grade copper ore was treated by atmospheric leaching and high-pressure oxidative leaching processes. A maximum recovery (>93.0%) of copper was obtained by high-pressure oxidative leaching in the water, whereas the copper recovery was lower than 12% in the sulfuric acid solution under atmospheric leaching conditions. The copper concentration in a pregnant leach solution enriched up to 15.0 g/L under the optimized leaching conditions. The effect of impurity such as iron in the sample on the froth flotation and both leaching processes is also considered. A process flow for the recovery of copper from silicate-containing low-grade copper ores is proposed as a result of these studies.</p>
