071063000 | Carbonates, oxides, sulfates, halides, etc. | 6 |
20110011142 | Material Compound and a Method of Fabricating the Same - A material compound comprising MgO. CaCO | 01-20-2011 |
20120031158 | CONTINUOUS PROCESS FOR PREPARATION OF CALCIUM THIOSULFATE LIQUID SOLUTION - An efficient process for the continuous preparation of calcium thiosulfate (CaS | 02-09-2012 |
20120131973 | Utilization of a Peridotite-type Rock for the Treatment of CO2 from a CO2-emitting Industrial Plant - A filter for treating CO2 from a CO2-emitting industrial plant, takes advantage of the fact that peridotite igneous rocks (or material of similar chemical content: basalt, gabbro, dunite, amphibolites, artificially produced Ca, Mg oxides) which are abundant on and close to the Earth's surface, can absorb and contain CO2 gases resultant from industrial activity. This chemical process occurs naturally, but has not been utilized to capture high concentrations of CO2 emitted into the atmosphere. Calcium and magnesium oxides of the peridotite react with CO2 to form stable carbonate minerals. The invention enhances and expedites this natural process for the remediation of industrial pollutants such as CO2 from the oil, gas, coal, cement/concrete and like CO2-emitting industries, and provides a resource for materials in construction (concrete), steel, aviation and agricultural and other industries. | 05-31-2012 |
20130167604 | Method for Producing Fertilizers Containing Dispersed Micronized Sulphur - A method of producing a fertilizer composition containing micronized sulphur wherein elemental sulphur is dissolved in anhydrous or hydrous ammonia to form an ammonia/sulphur solution and the ammonia/sulphur solution is reacted with an acidic component having at least one plant growth constituent to simultaneously form a sulphur composition comprising a sulphur compound and micronized sulphur. The thus formed fertilizer composition is dried and can be formed into various shapes such as pellets, prills, etc. | 07-04-2013 |
20140245804 | Magnesium Sulphate - The invention provides a method for the manufacture of a magnesium sulphate product, and a crystalline product, which comprises magnesium sulphate in the form of crystals or granules, as obtainable by carrying out this method. The method comprises the steps of: (a) providing a sulphuric acid product that has been obtained as a by-product during the sulphate process for manufacturing titanium dioxide; (b) concentrating the sulphuric acid product to obtain a concentrated product that has a higher sulphuric acid concentration; (c) combining a magnesium-based neutralising agent with the concentrated product and allowing the magnesium-based neutralising agent and the sulphuric acid to react, to generate magnesium sulphate in solution; and (d) crystallising magnesium sulphate out of the solution, to obtain a crystalline magnesium sulphate product together with a remaining liquor. The magnesium sulphate thus obtained may be mixed with an agriculturally acceptable carrier or diluent and/or with other fertiliser materials to produce a fertiliser. | 09-04-2014 |
20160075610 | PROCESS FOR PRODUCING A ZINC SULFATE SOLUTION, OBTAINED FROM STEELWORKS POWDER AND RESPECTIVE FERTILIZER INPUTS - The present application refers to zinc recovery process from steelworks powder, and to obtain a zinc sulfate solution with 12% Zn by weight with the expected degree for fertilizer. Such an approach can aim to add value to a steelmaking waste, by partially converting environmental liability in commercial product taking advantage of the steelworks' powder as a raw material for the production of a liquid fertilizer and ready for use, containing zinc and sulfur with low liquid effluent production. Such an approach can be advantageous as to simplicity, use of mild temperatures, use of a single reactant, overall conversion of the reactants into a product solution of commercial quality, ready for use as a foliar fertilizer with low generation of wastewater and without generation of additional waste. | 03-17-2016 |
