摘要： An electrowinning cell has anodes shielded by an electrical-flux-impervious, electrically non-conductive material which protectively covers each of the anode suspension members and adjoining upper margins of the main body of the anodes. At least one electrical-flux-pervious opening of proper shape, size, and appropriate position to permit sufficient current flux to flow to an associated cathode to induce a uniform current distribution on the upper portions of the cathode is provided for each suspension member. The resulting uniform current distribution insures deposition of highly pure metal values of uniform thickness without the usual undesirable extraneous formations on the top edge of the electrowon metal cathode. The shielding material may be applied to an anode before attachment to its hangerbar for suspension in an electrowinning cell or may be applied to an anode which is already in service.

摘要： An electrodeposition method in which high quality metal such as copper is produced on a non-retentive cathode blank at a high current density. A predetermined close cathode-anode spacing and a gas bubble tube for continuously agitating the electrolyte across the face of the cathode enable effective use of high current densities to electrowin or electrorefine a metal such as copper. Method includes maintaining anodes apart from cathodes at a predetermined close distance, optimally less than one inch face to face. Bubble tubes are positioned between cathode-anode pairs and are supported by bubble tube support members. For electrowinning, anode is provided with a non-conductive extension on its base and non-conductive convection baffles at opposite edges of its faces. Baffles and extension prevent electrodeposition on unwanted areas of cathode. Baffles, close spacing, and bubble tubes cause desired convection of electrolyte throughout cell. In an electrorefining cell, convection baffles are positioned on vertical support members within the tank.

摘要： Copper concentrate is mixed with iron and a fusible salt or fusible salt mixture which is molten at the roasting temperature. The mixture is roasted in a non-oxidizing atmosphere at a temperature below 475*C (preferably between 350*C-390*C) to produce a product containing free copper and pyrrhotite. The salt acts as a solvent for the reaction and enables copper to be recovered economically from copper concentrate without the evolution of sulfide pollutants into the atmosphere.

摘要： An improvement in processes for electrowinning copper from aqueous, sulfuric acid solutions comprises utilizing anodes of an alloy of lead and calcium containing from about 0.025 to about 0.1 percent calcium by weight. Anodes of the lead-calcium alloy have exceptionally superior resistance to corrosion in comparison to conventional lead or lead-antimony alloy anodes when used in electrowinning copper from sulfuric acid solutions.

摘要： AN IMPROVEMENT IN THE PROCESSING OF MOLYBDENITE ORE MATERIALS, USUALLY MOLYBDENITE-BEARING COPPER SULFIDE CONCENTRATES, FOR THE RECOVERY OF THE MOLYBDENUM VALUES CONTAINED THEREIN. INSTEAD OF THE CONVENTIONAL FLOTATION CIRCUIT, WHEREIN MIDDLINGS ARE RECIRCULATED AND MOLYBDENITE VALUES THEREIN RECOVERED IN A RELATIVELY HIGH GRADE MOLYBDENITE CONCENTRATE AS A FINAL PRODUCT MEETING ESTABLISHED SPECIFICATIONS AS TO MOS2 CONTENT, AND NORMALLY ALSO AS TO CHEMICAL GRADE, AT LEAST A PART OF THE MIDDLINGS ARE DRAWN OFF AS A RELATIVELY LOW GRADE MOLYBDENITE INTERMEDIATE PRODUCT AND ARE TREATED SEPARATELY FOR THE RECOVERY OF THE CONTAINED MOLYBDENUM VALUES. RECOVERY OF MOLYBDENUM VALUES IN TERMS OF BOTH HIGH GRADE CONCENTRATE AND THE LOW GRADE INTERMEDIATE PRODUCT IS SIGNIFICANTLY HIGHER THAN IS RECOVERY OF MOLYBDENUM VALUES IN TERMS OF THE CONVENTIONAL HIGH GRADE CONCENTRATE BASED ON THE CUSTOMARY RECIRCULATION OF MIDDLINGS.

摘要： A substantially dry intimate mixture of copper sulfide mineral concentrate and an added diluent material is contacted with at least a stoichiometric amount of chlorine relative to chlorinatable compounds of such materials at a temperature of between 300* and 400* C. to produce a reaction product containing water-soluble cupric chloride. Sulfur and iron values present in the mixture are substantially completely volatilized. Typical diluent materials are chlorinatable iron compounds, gangue materials, silica sand, and carbon. A portion of the diluent can be already present in the copper sulfide material, for example gangue components of a copper sulfide mineral concentrate, with the rest of the necessary diluent being added to form the mixture. The cupric chloride product recovered from the waterinsoluble residue in the reaction product as by means of water leaching is substantially uncontaminated by sulfur or iron values.

摘要： Metal values are extracted by a combination of slope caving and leaching from mineralized deposits at or near the surface of the earth that are uneconomic to work in normal ways either because of excessively low grade or access difficulties, e.g., areas normally encountered at the fringes of open pit mining operations. Undercutting of a slope to induce caving results in effective mass fragmentation of the mineralized material and the formation of a substantially unstratified and highly porous body of fragmented material at the foot of the slope. Application of a leach solution to such body, either as is or leveled and provided with superficial basins for holding a supply of the leach solution, so such solution percolates downwardly through the fragmented and unstratified material, extracts values therefrom which are recovered by collection and processing of the pregnant leach liquor.
