Patent CA-2522336-C (CA)
Title: Method for processing sulfide minerals and concentrates
Inventor: SHAPOVALOV VIATCHESLAV DMITRIEVICH
IPC: C22B3/44
Filed: 2003-04-16
Granted: 2010-04-06
Abstract: The method is referred to hydrometallurgical process and serves for recovery of nonferrous, rare and precious metals from sulfide minerals and concentrates. The invention is aimed at creating conditions for the most complete extraction of metals, preventing formation of elementary sulfur. The objective is attained by means of the following: the hydrometallurgical method of sulfide minerals and concentrates processing, which involves sulfide minerals oxidation in aqueous medium using nitrogen oxides, envisages that the sulfide materials containing slurry are subjected to oxidation of the sulfide and the oxidation is realized under controlled conditions of the slurry acidity, i.e. with constant neutralization of sulfuric acid formed as a result of the sulfides oxidation, moreover, sulfuric acid is neutralized to acidity level, at which no formation of elementary sulfur occurs, while natural or artificial substances, such as CaC03, MgC03, Ca(OH)2, CaO, NaOH, CaHP04 etc., are used as acidity neutralizers; the choice of a specific neutralizer is dictated by the necessity of formation of slurry neutralization products with assigned physicochemical properties: filterability, slurry thickening, arsenic substance insolubility, non~toxicity and other required properties. Oxidation of sulfide minerals is realized under agitation providing sufficient mass exchange and efficient occurrence of chemical reactions. Oxidation is realized in the temperature range of 20-90~C, mainly in the range of 65-85~C. The liquid-to-solid ratio may vary from 1:1 to 5:1, depending on effectiveness of the required precipitate formation and proceeding of sulfide oxidation reactions. Nitric and nitrous acids, as well as their oxides, mainly nitrous acid, HN02, and its oxide, N203, are used as oxidizing agents. Regeneration processes of NO to N203 are also described.

Abstract: Casing or other well tubulars that have failed are repaired in a manner that doesn't reduce the final inside diameter and doesn't further propagate the failure. The tubular needing repair is first expanded on at least one zone above and below the damaged area. This expansion in an undamaged area arrests failure propagation when the damaged area is then expanded. After the damaged area is expanded, the patch coupled preferably with exterior seals is positioned in the expanded zone of the damaged tubular and expanded. The procedure can also be accomplished in a single trip into the well.

Abstract: The present invention relates to a message delivery system and methods for delivering messages to a computing system. The system uses a message ID  structure and a message ID database to allow a user to check whether he or she is recipient of a new message without having to contact the message server that holds messages to be delivered. The resource load related to users checking for messages is therefore left to a separate computing system, allowing the message server to dedicate its resources to the receiving and delivering of messages.
