The present invention relates to a process for the preparation of articles of manufacture made of or based on sulphur, which comprises cooling of liquid sulphur in a volume of containment until the sulphur mass solidifies and forming of the product, characterised in that elastic pressure waves are applied to the cooling mass of liquid sulphur to produce a crystalline suspension of solid sulphur in liquid sulphur.. .
Method for improving selectivity and recovery in the flotation of nickel sulphide ores that contain pyrrhotite by exploiting the synergy of multiple depressants
A method of using the synergy of multiple depressants to improve the depression of iron sulphide without compromising the recovery of the valuable sulphide minerals in the flotation of non-ferrous metal sulphides, while reducing or eliminating the use of environmentally problematic chemicals such as polyamines. The method has significant economic and environmental benefits.
2-substituted-3-phenylpropionic acid derivatives and their use in the treatment of inflammatory bowel disease
The present invention relates to 2-(substituted sulphur, sulphone or sulphoxide)-3-(substituted phenyl)propionic acid derivatives, 2-(substituted oxygen)-3-(substituted phenyl)propionic acid derivatives, benzoic acid derivatives, and derivatives of 2-methyl-2-(phenoxy or phenylthio)propanoic acid and 2-(methyl or ethyl)-2-(phenoxy or phenylthio)butanoic acid, to processes for preparing such compounds, to their use in the treatment of inflammatory conditions, and to pharmaceutical compositions containing them.. .
Process for recovery of technical grade molybdenum from diluted leaching acid solutions (pls), with highly concentrated arsenic, from metallurgical residues
A method for recovering technical-grade molybdenum from diluted acid leaching solutions (pls) that have a high arsenic concentration is disclosed. The method includes: (a) bringing a pre-filtered acid leaching solution (pls), originating from the leaching of smelter dust, into contact with an anionic ion-exchange resin; (b) washing the loaded resin with water; (c) extracting molybdenum from the ion-exchange resin with an alkaline ammonium regenerant solution to form ammonium molybdenum in solution; (d) washing the unloaded resin with water; (e) adding iron and/or magnesium salts to the recovered ammoniacal solution to obtain a precipitate which is transferred to the arsenic abatement step and a solution containing ammonium molybdate in solution; (f) adding sulphuric acid to the arsenic-free ammoniacal solution in order to precipitate the moylbdenum in the form of ammonium molybdate; (g) separating the precipitate by filtering the molybdate and re-circulating the solution obtained with the initial pls solution; (h) calcining the separated precipitate to obtain ammonia and molybdenum trioxide; and (i) recovering the released ammonia for its subsequent use in the method as a recirculated regenerant solution..
