Definitions

  • the present invention is directed to an apparatus and method for achieving a chemical and/or physical change in matter, for example, in the conversion of minerals into preferred chemical feedstock and the breakdown of ores into their constituent elements.
  • acoustic (or ultrasonic) energy is applied to a liquid medium causing the formation of small bubbles or cavities (cavitation) which subsequently expand and explosively collapse.
  • cavitation The formation, expansion and ultimate collapse of the bubbles, known as cavitation, is accompanied by the release of intense vibrational energy.
  • the present invention provides a method of treating matter where said matter:
  • steps (i), (ii) and (iii) are conducted concurrently, however, steps (ii) and (iii) may be conducted intermittently during step (i).
  • the matter to be treated may be a single substance or a mixture of two or more substances.
  • the method of the invention may be a batch process or a continuous process.
  • the fluid is preferably aqueous in nature.
  • an electrolyte may be added to said matter.
  • the electrolyte may be acidic or alkaline in nature.
  • the electrolyte is a hydroxide.
  • the hydroxide is sodium hydroxide, however a hydroxide having a another counter ion may be adopted.
  • the hydroxide is added to initiate current flow through at least part of said fluid.
  • the hydroxide is added in an amount sufficient to initiate conductivity in the matter to be treated.
  • the fluid in combination with the matter to be treated may be in the form of, for example, a slurry, an emulsion, a dispersion or a suspension or the like.
  • the electric current may be alternating current (AC) or direct current (DC).
  • the current may be selected to have a desirable voltage, frequency and/or waveform.
  • the voltage may be about IV to about 50V.
  • the frequency may be up to about 50 MHz.
  • the current may be of any waveform such as, for example, a square or sinusoidal waveform. A square waveform is preferred..
  • the present invention provides an apparatus for treating matter where said matter:
  • (b) is combined with a fluid; said apparatus comprising: a vessel for containment of said matter; means for inducing cavitation in at least part of the fluid; means for generating shear; and at least two electrodes adapted to be held at a respective first and second predetermined voltage potential and located so as to allow a current to pass through at least one region in which at least part of said matter to be treated is located.
  • the apparatus is configured to allow the passage of an electric current through localised zones of cavitation and high shear. It appears that when material is subjected to tension or shear and an appropriate electric charge is applied to the material, the chemical bonds within the material are temporarily or permanently disrupted. The combined shear and suitable electric charge, coupled with cavitation significantly reduces the energy needed for comminution.
  • cavitation is induced by high speed rotation. Cavitation may also be induced by other means, for example, an external ultrasound device.
  • the vessel acts as an electrode.
  • the vessel may also be lined on the inner surface with a material that acts as the first electrode and the means for inducing cavitation acts as the second electrode.
  • the vessel may be of any desired configuration capable of retaining matter as the process is conducted either batchwise or continuously.
  • the vessel may be cylindrical, spherical or tubular in shape.
  • the vessel is of a cylindrical configuration.
  • the means for inducing cavitation may assume any one of a variety of configurations such as, for example, rotating disk(s) or impeller(s), baffle(s) or constriction zone(s), or any two or more of these configurations in combination.
  • Such disks, impellers etc. may have smooth or rough surfaces.
  • Such disks or impellers may have a wear resistant coating, or be fabricated out of wear resistant material, at regions in which high cavitation occurs.
  • wear resistant materials or coatings may be, for example, diamond, tungsten carbide, or ceramic or the like.
  • the means of inducing cavitation is a rotating disk.
  • the disk may have a substantially smooth circular periphery or the periphery of the disk may include at least one disconformity at which localised regions of cavitation are induced.
  • the disk may be coated, or fabricated from, a wear resistant material at and/or about these regions of disconformity.
  • the rotating disk may be welded to a substantially vertical shaft.
  • the rotating disk may be situated within and near the base of the vessel and rotates independently of the vessel.
  • the rotating disk may be positioned in a substantially horizontal orientation (i.e. about 90 degrees to the axis of the shaft) or may be inclined at less than about 90 degrees, such as, for example, 85 degrees to the axis of the shaft. Preferably, however, the rotating disk positioned in a substantially horizontal orientation.
  • the vessel and disk may rotate in the same direction or in opposing directions, however the vessel may be stationary.
  • the mode of operation of the vessel and/or disk depends on the particle size and/or density of the matter to be treated.
  • the vessel and/or rotating disk may be made of a material of a suitable electrical conductivity. Suitable electrical conductivities range from 0.05 to 10 ohms/m, however, preferably, the material has a conductivity of less than about 1 ohms/m.
  • the vessel may be lined with a material of a suitable electrical conductivity able to be held at a predetermined voltage potential.
  • the disk is preferably rotated at a relatively high velocity relative to the vessel and is such that a peripheral velocity of the matter is in excess of about 200 m/s.
  • the matter to be treated is subjected to mechanical shear forces and cavitation and is broken down into extremely fine material very quickly and with a much lower energy input compared to conventional comminution methods known in the art.
  • the method and apparatus of the present invention may be operated at any suitable temperature or pressure.
  • the method and apparatus may be operated at ambient or elevated pressure.
  • the vessel may be operated at about atmospheric pressure and about 8O 0 C.
  • the method and apparatus of the present invention may be used to achieve the physical (size) reduction of matter, initiate and/or accelerate chemical reaction(s) within matter.
  • applications involving "physical reduction” include the manufacture of printing inks such as ink jet ink and in toner production as these products require very finely dispersed material so as to achieve a high printing quality.
  • Other physical applications include the conversion of the structural nature of compounds, for example: the fibre composition of asbestos may be broken down into its constituent parts forming new structures of benign properties. The process may also be used to break down ore and extract various components sequentially. It can also be used in the manufacture of pharmaceuticals to produce finely divided or dispersed materials. Such finely divided pharmaceuticals can be readily absorbed through the skin or inhaled.
  • Finely divided material can be readily mixed through cream formulations.
  • applications involving chemical transformation include, but are not limited to, the breakdown of toxic hydrocarbons into benign species; the production of alcohol from carbonaceous matter; the cracking of hydrocarbons to lighter fractions; production of glasses and cement; processing of sewage and household waste; and in the complexing or extraction of heavy metals from ores or contaminated material.
  • the process may also be used in the production of various hydrocarbons from coal and also in the recovery of metals from metal oxides, or in the conversion of asbestos fibres into benign species.
  • the process may also be used for industrial processes involving nuclear fission and fusion and the reclamation of radioactive waste. This is facilitated by the ability of the device to be readily scaled-up to industrial proportions. .

  • the constituents in the slurry one at a time, are removed preferentially as they reach their soluble condition, ie., at an appropriate pH.
  • the order that the minerals in the slurry become soluble is a function of the ranking of the particular mineral on the galvanic table.

  • the pH is of such a value that allows a particular constituent of the mix to form a hydroxide
  • the pH will remain constant until that entire constituent has been consumed to form the hydroxide, (this is so for the operating parameters of this experiment, where the pH is slowly increasing).
  • the pH starts to rise again until the next constituent becomes soluble in solution. This process can continue until nothing but insoluble constituents, if any, remain.
