    Abstract: A method of mining is disclosed. The method includes mining material in a mine in accordance with a mine plan designed to maximise the financial performance of the mining operation at the mine. The mine plan is based on mining to at least produce: (i) recovery grade ore that is valuable and suitable for recovery processing and there is no net economic benefit in sorting the ore prior to recovery processing the ore; or (ii) waste material that is waste and there is no net economic benefit in sorting the material; or (iii) economically sortable ore wherein there is a net positive economic benefit in sorting the ore prior to recovery processing the ore

    Abstract: REFERIDO A UN CONTROLADOR DE FLUJO DE GAS DE FLOTACION PARA EL CONTROL DE FLUJO DE UN GAS DE FLOTACION HACIA UNA CELDA DE FLOTACION QUE SEPARA LOS MINERALES VALIOSOS Y OTROS MATERIALES EN EL MINERAL EN BRUTO TRITURADO. EL CONTROLADOR DE FLUJO DE GAS INCLUYE UNA VALVULA PARA EL CONTROL DEL FLUJO DE GAS A LA CELDA Y UN CAUDALIMETRO PARA SUPERVICION DEL FLUJO DE GAS A LA CELDA A TRAVES DE LA VALVULA. EL CAUDALIMETRO ES TAMBIEN PARA EL AJUSTE DE LA VALVULA SEGUN SE REQUIERA PARA CAMBIAR EL FLUJO DE GAS PARA SATISFACER LOS REQUISITOS DE FLUJO DE GAS PARA LA CELDA. TAMBIEN SE REFIERE A UNA CELDA DE FLOTACION QUE INCLUYE EL CONTROLADOR DE FLUJO DE GAS, UN SISTEMA DE CONTROL DE FLUJO Y UN METODO DE CONTROL DEL FLUJO DE GAS HACIA UNA CELDA DE FLOTACION CON UN CONTROLADOR DE FLUJO DE GAS

    Abstract: REFIERE A UNA PILA DE MATERIAL QUE VA A SER LIXIVIADO PARA RECUPERAR UN METAL VALIOSO DEL MATERIAL Y UN METODO PARA LA CONSTRUCCION DE LA PILA. LA PILA COMPRENDE LADOS Y UNA PARTE SUPERIOR Y UN SISTEMA PARA CONTROLAR EL FLUJO DE AIRE HACIA EL INTERIOR DE LA PILA. EL SISTEMA DE CONTROL DE FLUJO DE AIRE DISPONE UNA COMBINACION DE UNA BARRERA IMPERMEABLE AL AIRE EN MATERIAL POLIMERICO, UNA CAPA DE UN MATERIAL A PRUEBA DE PUNCION Y PANELES PREFABRICADOS IMPERMEABLES AL AIRE CONECTADOS ENTRE SI. EL METODO DE CONSTRUCCION DE LA PILA QUE COMPRENDE LOS PASOS; FORMAR LA PILA CON LADOS, TUBOS DE AIREACION, UN SISTEMA SUMINISTRO DE LIQUIDO A LA PARTE SUPERIOR DE LA PILA, Y UN SISTEMA QUE DRENA UNA SOLUCION DE LIXIVIACION CARGADA DE METAL, CONECTAR LOS OTROS COMPONENTES DE UN SISTEMA DE AIREACION POR CONVECCION NATURAL O FORZADO, COLOCAR LA BARRERA IMPERMEABLE AL AIRE AL MENOS A LOS LADOS DE LA PILA PARA MINIMIZAR O IMPEDIR COMPLETAMENTE EL FLUJO DE AIRE HACIA LA PILA. APLICA ESPECIALMENTE EN LA LIXIVIACION DE UN MINERAL DE SULFURO DE COBRE QUE CONTIENE LA CALCOPIRITA , MINERAL DE COBRE, COMO UNA PARTE DEL MINERAL

    Abstract: An in-situ sampling and analysis system 10 is supported by a drill rig 12. The system 10 incorporates a frame 26 which carries equipment capable of sampling and analysing drill cuttings produced during drilling. This equipment includes a drill cutting handling system 28 and an emission spectrometer 30. The frame 26 is moveable to an operational position which facilitates the acquiring samples of the drill cuttings and conducting an elemental analysis of the cuttings. Prior to the drill rig 12 being trammed to the desired location for drilling of a further hole, the frame 26 is elevated with respect to the operational position to retract the equipment from ground level. The sampling of drill cuttings and determination of the composition of a mineral body is performed in real time simultaneously with the drilling.
