摘要： An environmentally compatible, industrially safe, and potentially economic means for recovering copper and/or nickel from deep-seated deposits without resorting to extensive underground development. A two-phase ammoniacal leach solution containing oxygen bubbles is forced under high pressure through an injection hole several thousand feet deep into a leaching interval of a deep lying deposit containing copper or nickel or copper and nickel. The two-phase leach solution travels through the leaching interval of the deep lying deposit and is pumped out of withdrawal holes spaced apart from the injection hole.The two-phase leach solution under high pressure (more than 500 psi) penetrates the deposit through cracks, fissures and fractures, leaching copper and/or nickel along the way. Under a controlled pressure gradient, the leaching solution migrates over a period of time to receiving holes from which the pregnant leaching solution is withdrawn. The pregnant solution is then processed for recovery of copper or nickel or copper and nickel before it is returned to an injection hole.A method and apparatus for producing the two-phase leach solution and for maintaining a system in which the gas bubbles are able to penetrate the deposit is disclosed.Also disclosed are various parameters, such as hole spacing techniques, hole completion techniques and stimulation techniques.

摘要： A process is disclosed for in-situ mining of copper from a subterranean ore body characterized, at least in part, by the presence of a sulfidic ore and by natural, microscopic fracture openings. The process comprises forcing a stable, two-phase lixiviant comprising an aqueous phase, a multiplicity of gaseous, oxygen-containing bubbles having a size sufficient to pass through the natural fracture openings in the ore body, and a surfactant for enhancing the formation of the bubbles and for minimizing bubble coalescence through the ore body to leach copper.The aqueous and gaseous phases of the lixiviant are mixed at the surface and injected into the leaching interval through an injection hole, or preferably, are mixed in a subterranean sparger within the hole above the leaching interval. The pregnant liquor is recovered through one or more production holes and, after the copper is recovered, the lixiviant may be reconstituted and recirculated.

摘要： A circulation tubing string is disposed about the lixiviant return tubing string in the production hole of an in situ minefield. The circulation string extends from the surface to a point near a packer which defines the top of the leaching interval. A fluid coupler provides a fluid flow path between the annular cross-section regions between the production hole casing and the circulation string, and between the circulation string and the lixiviant return string. A flow of cooling fluid is maintained from the surface through the circuital path defined by the annular cross-section regions and the fluid coupler, particularly including the exterior surface of the production tubing string. The fluid is maintained at a temperature and flow rate so that the pregnant leach liquor flows in the production tubing string between the leaching interval and the surface is characterized by a predetermined temperature drop.

摘要： System for removal of targeted pollutants, such as oxides of sulfur, oxides of nitrogen, mercury compounds and ash, from combustion and other industrial process gases and processes utilizing the system. Oxides of manganese are utilized as the primary sorbent in the system for removal or capture of pollutants. The oxides of manganese are introduced from feeders into reaction zones of the system where they are contacted with a gas from which pollutants are to be removed. With respect to pollutant removal, the sorbent may interact with a pollutant as a catalyst, reactant, adsorbent or absorbent. Removal may occur in single-stage, dual-stage, or multi-stage systems with a variety of different configurations and reaction zones, e.g., bag house, cyclones, fluidized beds, and the like. Process parameters, particularly system differential pressure, are controlled by electronic controls to maintain minimal system differential pressure, and to monitor and adjust pollutant removal efficiencies. Reacted sorbent may be removed from the reaction action zones for recycling or recycled or regenerated with useful and marketable by-products being recovered during regeneration.

摘要： A method of isolating a contaminated geological formation or aquifer is disclosed in which the formation is encapsulated by impermeable barriers. A grid of wells is drilled into the formation. A horizontal barrier is formed below the contaminated formation by creating an overlapping pattern of horizontally-oriented fractures filled with polymer radiating from each of these wells. A horizontal barrier may also be formed above the top surface of the contaminated formation if necessary. A ring of boundary wells may also be drilled surrounding the contaminated formation. The strata around each boundary well are fractured, and a polymer is then injected to form a vertical barrier around the periphery of the contaminated formation. In addition, water may be injected under pressure into guard wells between the contaminated formation and the vertical and/or horizontal barriers to further reduce any migration of pollutants into neighboring formations.

摘要： Metal values are solubilized from ore by a lixiviant having a pH from 5 to 8, comprising an aqueous solution of a chloride salt and a hypochlorite salt. Cyanuric acid may be added to retard decomposition of the lixiviant. In one alternative embodiment, any remaining hypochlorite ions are then eliminated by adding hydrogen peroxide or a reducing agent to the pregnant lixiviant. Metal values are recovered by reduction using carbon, electrowinning, or other conventional techniques. In an alternative embodiment for extraction of gold or silver, the steps are combined by using finely ground ore containing sulfides or carbonaceous material to both reduce any remaining hypochlorite ions and precipitate the metal values from the lixiviant. The lixiviant can then be regenerated either by electrolysis or addition of hypochlorite salt.
