    摘要： Collector compositions of a mixture of a C6 to C22 fatty hydroxamic acid and an oil for use in a method the removal of impurities from mineral ores by the froth flotation method. The collectors are prepared by reacting an ester of a C6 to C22 fatty acid with a hydroxylamine salt and a base in the presence of an oil and water to produce an alkyl hydroxamate salt; acidifying the alkyl hydroxamate salt, forming an organic layer and an aqueous layer, wherein the organic layer contains a C6 to C22 fatty hydroxamic acid substantially free of starting esters and hydrolysis and transesterification products of the ester; and separating the organic layer from the aqueous layer to provide a collector composition of the C6 to C22 fatty hydroxamic acid and the oil.

    摘要： A process for the recovery of minerals from the fine particle size fraction of froth flotation feed (slimes), which is conventionally discarded to waste because slimes interfere with efficient flotation. In the disclosed process, the slimes, which also may be termed fines, are scrubbed to clean the slimes, and are then subjected to conventional froth flotation. The scrubbing is done in the presence of an attrition media, in addition to chemical reagents for cleaning and dispersing fine particles. Thus an inert attrition media, of larger particle size than the slimes, is introduced into a scrubber. The process accordingly recovers a fine fraction of the flotation feed that is normally lost. The recovery process may be incorporated into an existing plant design, or as part of a new plant designed to recover material previously discarded in waste disposal areas.

    摘要翻译： 从泡沫浮选原料（泥浆）的细粒度部分回收矿物的方法，由于泥浆干扰高效浮选，其通常被丢弃以浪费。 在所公开的方法中，还可以将可称为细粒的泥浆擦洗以清洁泥浆，然后进行常规泡沫浮选。 洗涤在除磨介质的存在下进行，除了用于清洁和分散细颗粒的化学试剂外。 因此，具有比泥浆更大粒度的惰性磨耗介质被引入洗涤器中。 因此，该方法恢复通常丢失的浮选进料的细小部分。 回收过程可以并入现有的设备设计中，或作为设计用于回收先前在废物处理区域中废弃的材料的新设备的一部分。

    摘要： Methods of increasing the rate of separating hydrophobic and hydrophilic particles by flotation have been developed. They are based on using appropriate reagents to enhance the hydrophobicity of the particles to be floated, so that they can be more readily collected by the air bubbles used in flotation. The hydrophobicity-enhancing reagents include low HLB surfactants, naturally occurring lipids, modified lipids, and hydrophobic polymers. These methods can greatly increase the rate of flotation for the particles that are usually difficult to float, such as ultrafine particles, coarse particles, middlings, and the particles that do not readily float in the water containing large amounts of ions derived from the particles. In addition, new collectos for the flotation of phosphate minerals are disclosed.

    摘要： A method for optimising a mineral recovery process. A slurry 10 is fed to a conditioning step 20. The condition slurry 30 is then provided to a flotation circuit 40 to recover a concentrate 50. The remainder of the slurry is then rejected as tail 60 or passed for further processing. The present invention provides apparatus for analysing a sample stream 100 of the slurry. A sample stream 100 is provided to an analysis device 200 which treats the sample with an oxidising gas similar to the oxidative treatment 20. Several parameters are measured before and/or after the oxidative treatment of the slurry. The flotability characteristic of the slurry is then determined as a function of the measured parameter(s). The result is used to optimise mineral recovery. This apparatus can be used intermittently or continuously to provide on-going optimisation of the mineral recovery circuit.

    摘要： A process for floating fine particles containing metal values of an iron-bearing sulphide mineral ore including the steps of conditioning the aqueous pulp of ore at a pH of between about 7 and about 10 with a reducing agent which is preferably oxy-sulphur compound which dissociates to form oxy-sulphur ions having the general formula: SnOyz− where n is greater than 1; y is greater than 2; and z is the valance of the ion. A suitable collector is then added to the conditioned aqueous pulp to further condition the pulp and the pulp potential of the pulp raised to a sufficient level for the collector to adsorb onto the sulphide mineral ore. Gas is then bubbled through the aqueous pulp to subject the pulp to froth flotation. The froth from the flotation process is recovered to produce a concentrate of fine sulphide mineral and other metal values. By conditioning the aqueous pulp at a pulp potential which dissolves the iron hydroxide film from the surface of the metal sulphide inclusions in the ore and subjecting the ore to froth flotation at a suitable pulp potential before the iron hydroxide can reform, the recovery of metal values in the fine ores can be greatly enhanced.
