| 20110186660 | SORTING MINED MATERIAL - A method of sorting mined material to separate the mined material into at least two categories is disclosed. The method comprises exposing particles of the mined material to microwave energy and heating the particles depending on the susceptibility of the material in the particles. The method also comprises thermally analysing the particles using the temperatures of the particles as a basis for the analysis to indicate composition differences between particles and then sorting the particles on the basis of the results of the thermal analysis. The method also comprises compensating for temperature variations in the mined material that is supplied to the method. | 08-04-2011 |
| 20110175429 | MINING SYSTEM - A method of mining ore in a mine pit ( | 07-21-2011 |
| 20110174904 | SORTING MINED MATERIAL - A method of sorting mined material to separate the mined material is disclosed. The method comprises exposing particles of the mined material to microwave energy and heating the particles depending on the susceptibility of the material in the particles. The method also comprises thermally analysing the particles using the temperatures of the particles as a basis for the analysis to indicate composition differences between particles. The thermal analysis step includes thermally assessing particles against a background surface. The thermal analysis step also includes heating the background surface to a temperature that is different to the temperature of the particles to provide a thermal contrast between the particles and the background surface. The method also comprises sorting the particles on the basis of the results of the thermal analysis. | 07-21-2011 |
| 20110113928 | LEACHING ORES - A process for leaching an ore containing sulphidic copper-containing minerals is disclosed. The process includes carrying out an aerated oxidising leach of a part of the ore and causing reactions with a source of iron such as pyrite in the ore and producing an acidic leach liquor containing ferrous ions, ferric ions, and copper ions in solution. The process also includes carrying out a leach of another part of the ore using the leach liquor produced in step (a) under conditions that minimise reactions with a source of iron such as pyrite in the ore and producing a leach liquor containing copper ions in solution. | 05-19-2011 |

| 20100206778 | Sorting Mined Material - A method of sorting mined material for subsequent processing to recover valuable material, such as valuable metals, from the mined material is disclosed. The method includes a combination of selective breakage of mined material (for example, by using microwaves and/or high pressure grinding rolls), subsequent size separation, and then particle sorting of a coarse fraction of the separated material based on differential heating and thermal imaging. | 08-19-2010 |
| 20100154536 | GRAVITY GRADIOMETER - A gravity gradiometer is disclosed which has a sensor in the form of bars ( | 06-24-2010 |
| 20100044935 | DIRECT SMELTING VESSEL AND COOLER THEREFOR - A direct smelting vessel and a hearth cooler element are disclosed. The vessel includes a refractory lined hearth. An inner surface of an upper part of the hearth extends upwardly and outwardly to side walls of the vessel. The upper part of the hearth incorporates a hearth cooler disposed outwardly behind the refractory lining of that part of the hearth and below the cooling panels on the side walls of the vessel. The hearth cooler comprises a plurality of cooler elements. Each cooler element has a hollow open-backed shell structure having base, top and side walls formed integrally in a cast structure and incorporating coolant flow passages. | 02-25-2010 |
| 20090293671 | Electric Arc Furnance Steelmaking - Efficient coordination of processing (by desulphurising) and moving hot metal from a direct smelter, producing hot metal on a continuous basis, to an electric arc furnace DIRECT or furnaces, operating on a batch basis, is disclosed. The invention includes the use of hot metal storage devices, such as ladles, that are large enough to supply hot metal for a small number, preferably two or three, of electric arc furnace batch operations. | 12-03-2009 |
