摘要： Pretratamiento o proceso previo a la flotación de minerales, que permite la extracción parcial o total de bitumen u otros elementos orgánicos que forman parte de la mineralización, los que interactúan negativamente con el proceso de flotación. El pretratamiento consiste en la mezcla del mineral con agua, y la adición de una base fuerte. Luego de un tiempo de agitación y burbujeo, se produce la separación de los elementos orgánicos, los que debido a su hidrofobicidad suben a la superficie y son retirados. Junto con los elementos orgánicos, también son arrastradas partículas del mineral de interés económico. Por ello, se consideran etapas de limpieza que permiten retornar este mineral al proceso. Al terminar el pretratamiento, se logra que el mineral tenga menores contenidos de elementos orgánicos, lo que facilita el proceso de flotación del mineral: Mejoran sus indicadores: recuperación, ley del concentrado, consumo de reactivos.
摘要翻译：预处理或预矿物浮选工艺，其允许部分或全部提取作为矿化部分的相互作用的沥青或其他有机元素。对浮选过程有负面影响。预处理包括矿物与水的混合物，以及加入强碱。经过一段时间的搅拌和鼓泡后，发生了有机元素的分离，这是由于它们的疏水性上升到表面并被除去。随着有机元素，经济矿石颗粒也随之而来。因此，考虑允许这种矿物返回到该过程的清洁阶段。预处理完成后，获得的矿物有机元素含量较低，有利于矿物浮选过程：提高其指标：回收率，浓缩规律，试剂消耗量。

摘要： A method of treating value bearing material comprising oxidised or surface oxidised mineral values includes the steps of crushing the value bearing material, contacting the crushed material! with a sulfide solution to sulfide the oxidised or surface oxidised mineral values, and adding ions of a selected base metal to the crushed value bearing material. The value bearing material may comprise oxidised or surface oxidised base metal or precious metal minerals. The crushed value bearing material is prepared as a slurry or pulp comprising from 15% to 40% solids and the remainder comprising water. The sulfide solution preferably comprises a soluble sulfidiser such as sodium hydrosulfide and the base-metal ion solution preferably comprises metal salt of base metals 'like copper or iron. In a preferred embodiment of the method, the sulfide ion concentration in the slurry is measured with an ion- specific probe which measures the sulfide ion concentration as a potential, and the quantity of sulfidiser solution in the slurry is adjusted to maintain the measured sulfide ion concentration at or near the predetermined value. The invention extends to an installation for treating value bearing material according to the method.

摘要： An apparatus (10) for recovering a desired fraction of a raw material bearing the desired fraction includes a vessel or cell (12) defining a treatment chamber (14) therein and an inlet (22) into the chamber (14) for introducing a slurry of raw material to be treated into the chamber (14). An attrition zone (16) is defined in a portion of the chamber (14) near the inlet (22) in the flow path of material introduced into the chamber (14) so that particles of the raw material are caused to impact against each other. A flotation zone (18) is defined in a distal portion of the chamber (14), in flow communication with the attrition zone (16), in which the attritioned particles are contacted with gas bubbles (26). This forms a froth phase (28) separated from the slurry by a slurry-froth interface such that the desired fraction is either selectively taken up into the froth phase (28) by the gas bubbles or selectively left behind in the slurry. The froth phase (28) flows from the chamber (14) via an appropriate outlet (36).

摘要： A method and apparatus in which fibrous waste is processed under initial overpressure conditions is disclosed. Once the fibrous waste has been loaded into an autoclave (14), a compressor (12) pressurizes the chamber, following which caustic swelling and debonding solution (16) is injected into the chamber. In a further embodiment, a caustic solution (16) is introduced into the fiber slurry output from an initial separation stage, following which negative pressure is maintained for a period of time chosen to enhance the desired debonding. In yet another embodiment of the present invention, de-inking solution is introduced into an initial fibrous waste processing stage which operates at super- or sub-atmospheric pressure.

摘要： The present invention relates to an apparatus and method for separating and processing solid waste, often but not necessarily from municipalities (and so will be generically referred to herein as municipal solid waste or "MSW"), into useful products, and for reducing biohazards and putrid odors derived from MSW. The MSW is loaded into an elongated, generally cylindrically shaped rotating pressure vessel (10) and is subjected to heat and pressure by the application of steam (40) in specified amounts to break down the organic portion of the MSW into a cellulose feedstock, or a de-manufactured paper product, of uniform particle size and density. This product is then easily separable from other constituents of MSW, such as glass, aluminum and other metals, and plastics. The recyclables are recovered and sold in the market. The waste water from the process is reduced by processing through a water vamping apparatus (50).

摘要： A differential density alteration (DDA) device (439) to enable the separation and partitioning of particles of one or more selected members of plastics (408, 540, 550) included in a mixture of a plurality of different plastics in which each member of the plurality of different plastics is divided into discrete particles. The DDA device (439) heats (514) the mixture to a temperature for a time that causes the particles of the one or more selected members (408, 540, 550) to alter in such a way that the difference between the apparent density of the particles of the selected one or more members and the apparent density of particles of the other members of the mixture (the differential density), after heating (514), is different from the differential density before heating, whereby the alteration in differential density produces a differential density alteration (DDA). A plastics density separator (419, 518), having a suitable partition curve, will separate and partition the selected particles of the selected one or more altered plastics members from the altered mixture with improved efficiency and precision.
