Definitions

  • This invention relates to a process of agglomerating particulate material and to articles produced by agglomerating particulate material.
  • Particulate material and particularly particulate material emanating from industrial processes often have commercial value.
  • dust or fines generated in mineral beneficiation plants by abrasion as ore is transported contains traces of minerals. This dust cannot be introduced into furnaces because updrafts within the furnaces channel the dust into the chimney and into the atmosphere.
  • dust produced in the mining, transporting and working of coal, coke and other solid combustible fuels is also lost.
  • waste particulate material it is also often desirable to utilise waste particulate material to produce bricks and building blocks thereby conserving natural resources conventionally used to produce such items.
  • waste particulate material it is desirable to agglomerate solid, particulate, hazardous waste material to facilitate storage and handling.
  • agglomerating particulate waste material is to embed the material in cement, usually portland cement. This does tend to be expensive however and the expense can often negate the beneficial aspects of agglomeration. In addition, when solid, particulate, hazardous waste is embedded in cement it can leach out of the agglomeration which, to a large extent, also negates the process.
  • the particulate material is metallurgical fines, particularly chromium metal oxide fines, alternatively platinum tailing oxide fines, further alternatively gold tailing fines, and for the desired shape into which the slurry is formed to be a block which is suitable for introduction into an ore beneficiation process.
  • the particulate material to be combustible fuel dust, particularly coke dust, alternatively coal dust, further alternatively charcoal dust, and for the desired shape into which the slurry is formed to be a block, alternatively a brick, further alternatively a briquette, all of which are suitable for introduction into a furnace or a domestic fire.
  • the particulate material to be sand, material from mine dumps or the like and for the desired shape into which the slurry is formed to be a building brick, alternatively a building block.
  • the particulate material to contain matter which is classified as hazardous to human or animal health and for the desired shape into which the slurry is formed to be any shape suitable to facilitate storage of said particulate material.
  • the mixture to contain an accelerator in the form of an alkali, preferably an hydroxide, further preferably a metal hydroxide.
  • the mixture to contain, if required, a decelerator in the form of a carbon compound and preferably an organic carbon compound.
  • the slurry when shaped, to be cured at a temperature in excess of 25 degrees centigrade, and preferably at a temperature of between 40 degrees centigrade and 50 degrees centigrade.
  • the slurry to incorporate, in the shaping stage, reinforcing and other elements which are embedded in the cured agglomerate.
  • the invention also extends to a shaped article produced in accordance with the above described method.
  • Example 1 is an embodiment in which titanium dust is agglomerated for beneficiation
  • Example 2 is an embodiment in which solid, combustible fuel dust is agglomerated for use as a fuel
  • Example 3 is an embodiment in which metallurgical slags are agglomerated for use in the building industry.
  • a process for the agglomeration of particulate material in this example, titanium dust or slag obtained from a titanium extraction plant, comprises the steps of mixing collected titanium particulate material with sodium silicate and an accelerating agent in the form of sodium hydroxide.
  • the titanium is in the form of a slag so water need not be added to form a slurry.
  • the slurry obtained as described above is then formed into bricks which are substantially the same size and shape as bricks used for building and the bricks are left to cure for 8 hours at 40 degrees centigrade. Once cured the bricks can be stockpiled before being channelled through a titanium extraction plant.
  • a process for agglomerating a solid, combustible fuel dust comprises the steps of mixing the coal with water, sodium silicate, sodium hydroxide, electric arc furnace dust, chromite ore, fly ash and granulated blast furnace slag powder to form a slurry which is formed into bricks and cured at 50 degrees centigrade for 8 hours.
  • the bricks so formed can also be stockpiled and used in a furnace thus making the coal available for use.
  • charcoal fines can be used instead of the Duff coal and that briquettes for use in the domestic environment for heating or cooking as opposed to industrial furnaces can be formed.
  • Example 3 a process for agglomerating a metallurgical slag in particulate form to form blocks for use in the building industry is described.
  • the slag which contains heavy metal oxides, is mixed with sodium silicate and sodium hydroxide.
  • sodium silicate and sodium hydroxide As in the previous example.
  • the resulting slurry is moulded to form bricks or hollow building blocks and cured at 40 degrees centigrade for 8 hours before being suitable for use.

Abstract

L'invention concerne un procédé permettant d'agglomérer ce que l'on considère généralement des déchets particulaires avec un liant à base de silicate de sodium afin de leur conférer une forme utile. Dans un mode de réalisation, le matériau particulaire est constitué de fines de métal précieux qui, une fois agglomérées, peuvent être introduites dans un processus d'enrichissement de minerai. Dans un autre mode de réalisation, Il peut s'agir de poussière de combustible qui, une fois agglomérée, peut être utilisée comme combustible solide. Dans un autre mode de réalisation encore, une fois aggloméré, le matériau particulaire peut être utilisé comme blocs ou briques de construction. En outre, les matériaux particulaires dangereux peuvent être agglomérés, ce qui facilite leur stockage.
