| 21 | METHOD FOR FORMING METAL FLUORIDE MATERIAL | US14221957 | 2014-03-21 | US20140284526A1 | 2014-09-25 | Jon Shan |
| The present invention is directed to processing techniques and systems of metal fluoride based material, including but not limited to nickel difluoride, copper difluoride, manganese fluoride, chromium fluoride, bismuth fluoride, iron trifluoride, iron difluoride, iron oxyfluoride, metal doped iron fluorides, e.g., FexM1-xFy (M=metals, which can be Co, Ni, Cu, Cr, Mn, Bi and Ti) materials. An exemplary implementation involves mixing a first compound comprising a metal material, nitrogen, and oxygen to a second compound comprising hydrogen fluoride. The mixed compound is milled to form metal fluoride precursor and a certain byproduct. The byproduct is removed, and the metal fluoride precursor is treated to form iron trifluoride product. There are other embodiments as well. | ||||||

| A process is disclosed for separation and recovery of vanadium, molybdenum, iron, tungsten, cobalt and nickel from alumina-based materials, mattes, ores, manufacturing by-products and waste. These elements are oxidized. The oxides are reacted with gaseous HCl to form volatile chloride-bearing compounds that subsequently sublimate. The volatile compounds are condensed in a downward-stepped thermal gradient that allows collection of moderate to high purity compounds of individual elements with exception of a nickel-cobalt co-condensate. Nickel is separated from cobalt by precipitation of nickel chloride from concentrated HCl pressurized with gaseous HCl. | ||||||

| 25 | Telescoped multiwall nanotube and manufacture thereof | US11080010 | 2005-03-14 | US20060057383A1 | 2006-03-16 | John Cumings; Alex Zettl; Steven Louie; Marvin Cohen |
| The invention relates to a method for forming a telescoped multiwall nanotube. Such a telescoped multiwall nanotube may find use as a linear or rotational bearing in microelectromechanical systems or may find use as a constant force nanospring. In the method of the invention, a multiwall nanotube is affixed to a solid, conducting substrate at one end. The tip of the free end of the multiwall nanotube is then removed, revealing the intact end of the inner wall. A nanomanipulator is then attached to the intact end, and the intact, core segments of the multiwall nanotube are partially extracted, thereby telescoping out a segment of nanotube. | ||||||

| The method of determining the extent to which a nickel structure has been attacked by a halogen containing gas to which it has been exposed which comprises preparing a quantity of water substantially free from dissolved oxygen, passing ammonia gas through a cuprammonium solution to produce ammonia substantially free from oxygen, dissolving said oxygen-free ammonia in said water to produce a saturated aqueous ammonia solution free from uncombined oxygen, treating at least a portion of said nickel structure of predetermined weight with said solution to dissolve nickel compounds from the surface of said structure without dissolving an appreciable amount of said nickel and analyzing the resulting solution to determine the quantity of said nickel compounds that was associated with said said portion of said structure to determine the proportion of combined nickel in said nickel structure. | ||||||

| 28 | Recovery of metal values from ocean floor nodule ores by halidation in molten salt bath | US30973872 | 1972-11-27 | US3894927A | 1975-07-15 | KANE WILLIAM S; MCCUTCHEN HUGH L; CARDWELL PAUL H |
| This invention provides a process for removing metal values from ocean floor nodule ores comprising contacting the nodule ore with a molten bath of an alkali metal halide and/or an alkaline earth metal halide to form the halides of the manganese, copper, cobalt and nickel present in the ore, and separating the thus formed halides from the reaction mixture, as by vaporization. The mixture of halides can then be separated into the individual halides, e.g. by dissolving in water and separating by extraction. Preferably the ore is first dehydrated and the ore can be contacted with a reducing agent to reduce the manganese present to the divalent state.

| Metals are extracted from ores which exist in the form of oxides or sulphides, by treating the ore with hydrogen fluoride and/or fluorosilicic acid. There are two preferred forms. When hydrogen fluoride is used, the ore is initially crushed, dried and then contacted with HF gas at temperatures above 105<o>C to produce metal fluorides. The metal fluorides are then contacted with aqueous HF solution and the resulting insoluble metal fluorides and iron oxides are separated from the solution, and metal fluorides preferably including nickel and cobalt fluorides are recovered. When fluorosilicic acid is used, the crushed and dried ore is directly contacted with an aqueous solution of fluorosilicic acid at temperatures above 70<o>C and the resulting insoluble metal fluorides and iron oxides are separated and metal fluorides preferably including nickel and cobalt fluorides are recovered. Preferred ores are cobalt-nickel lateritic ores. | ||||||
