Abstract: A method of inhibiting leakage of a fluid through a defect (4) in a wall of a pipe (2), comprising the steps: introducing a loss control medium (30) into a first portion of a pipe (2); conveying the loss control medium (30) along the pipe from the first portion to a second portion of the pipe, wherein the second portion is embedded in a porous medium and has a defect (4) through which fluid conveyed by the pipe during normal use leaks into the porous medium; and applying a pressure to the loss control medium (30) such that at least a portion of the loss control medium (30) is expelled from the pipe through the defect (4) into the porous medium thereby causing the loss control medium to accumulate within the porous medium in the vicinity of the defect which inhibits flow of a liquid through the defect into the porous medium.

Abstract: A flash steam powered flywheel turbine is provided comprising a stator housing with an internal channel for the flash and expansion of steam, the channel having a plurality of jet orifices to direct jets of expanding steam toward a rotary flywheel which is fixed to a rotational shaft within the stator housing. The rotary flywheel. is fitted with a plurality of inlet jet passages generally extending radially inwardly from the peripheral surface of the flywheel and oriented such that the force of expanding and impinging steam causes the flywheel to rotate about its central axis. Each inlet jet passage merges into one or more outlet jet passages oriented generally laterally such that the force of discharging steam causes further rotation in reaction to the discharging steam. The discharging steam is directed against steps or depressions formed on the inner lateral walls of the stator housing to add a jet-propulsion effect.

Abstract: The present invention relates generally to a process for recovering copper and/or other metal values from a metal-bearing ore, concentrate, or other metal-bearing material using pressure leaching and direct electrowinning. More particularly, the present invention relates to a substantially acid-autogenous process for recovering copper from chalcopyrite-containing ore using pressure leaching and direct electrowinning in combination with a leaching, solvent/solution extraction and electrowinning operation. In accordance with one aspect of the process, at least a portion of the residue from the pressure leaching operation is directed to a heap, stockpile or other leaching operation.

Abstract: The present invention is directed to a system for recovering metal values from metal-bearing materials. During a reactive process, a seeding agent is introduced to provide a nucleation site for the crystallization and/or growth of solid species which otherwise tend to passivate the reactive process or otherwise encapsulate the metal value, thereby reducing the amount of desired metal values partially or completely encapsulated by such material. The seeding agent may be generated in a number of ways, including the recycling of residue or the introduction of foreign substances. Systems embodying aspects of the present invention may be beneficial for recovering a variety of metals such as copper, gold, silver, nickel, cobalt, molybdenum, zinc, rhenium, uranium, rare earth metals, and platinum group metals from any metal-bearing material, such as ores and concentrates.

Abstract: The present invention relates generally to a process for the production of sulfuric acid and liberation of precious metal values from materials containing sulfur through pressure leaching operations. In accordance with various aspects of the present invention, the sulfur-bearing materials may comprise residues from pressure leaching operations, such as those carried out at medium temperatures. The process of the present invention can be advantageously used to convert such sulfur-bearing materials to sulfuric acid by means of pressure leaching. The sulfuric acid so produced can be used beneficially in other mineral processing operations, for example those at the site where it is produced. Metals, such as precious metals, that are contained within the sulfur-bearing materials advantageously may be recovered from processing products by established precious metals recovery technology.
