Abstract

The present invention relates to a wear sensor, a method for sensing wear occurring to an object, and an equipment subject to wear. The present invention further relates to a wear sensing system comprising the wear sensor and a measuring device for measuring an amount of wear occurring to an object. The wear sensor comprises an electrical circuit comprising a sequence of discrete elements, each discrete element being capable to temporarily hold a digital data value, wherein the electrical circuit is configured to sequentially transfer the digital data value from a first discrete element on a first edge of the wear sensor to subsequent discrete elements toward a second edge of the wear sensor, wherein each discrete element is capable of being electrically decoupled from the electrical circuit, sequentially in a direction from the second edge by action of wear on the wear sensor. A number of discrete elements in the sequence is reduced when wear occurs on the wear sensor.

Abstract

A system and method for controlling the operation of a gyratory rock crusher is shown and described. The gyratory rock crusher includes a variable frequency drive that allows the eccentric speed of the gyratory crusher to be modified based upon sensed parameters of the rock crushing system. The speed of the eccentric rotation can be dynamically adjusted to compensate for the size of the material particles being crushed and the availability of the material. The use of the variable frequency drive increases the operating efficiency of the gyratory crusher by controlling the discharge flow rate of the crushed material from the crusher and thus allows for a reduction in the size of the discharge hopper. The rotational speed of the eccentric is controlled to be below the critical speed for the gyratory crusher.

Abstract

A gyratory crusher and a spider bushing assembly for supporting a spider bushing within the central hub of a gyratory crusher. The spider bushing assembly includes a spider bushing and a means for adjusting the distance between the outer flange of the spider bushing and a support shoulder formed within the central hub of the spider. The means for adjusting allows the position of the spider bushing within the internal bore of the central hub to change while maintaining an interference fit as a result of wear following use of the gyratory crusher. In one embodiment, one or more annular shims are positioned between the bearing support shoulder of the central hub and the outer flange of the spider bushing. Upon wear, one or more of the shims can be removed to improve the interference fit between the spider bushing and the internal bore formed within the central hub.

The pattern in which the holes are arranged in each of the respective groups of holes is elliptical having a center and a major axis which is substantially parallel to the radius and placed at a distance therefrom. The leading edge is, in the direction of rotation, behind an imaginary radial line intersecting the central axis of the shaft and the center of the ellipse, the leading edge being at an angle of 50°±2° in relation to the radial line. The area of the blade is divided into four planar portions by three straight bends.

Abstract

A presentation module is provided for presenting a fluid sample to a Laser-induced breakdown spectroscopy (LIBS) analysis. The presentation module comprises an inlet for admitting a fluid sample flow from a process flow, a measurement opening for co-operating with measurement optics, and a stabilizer surface facing towards the measurement opening. The stabilizer surface is adapted to form a stabilized sample flow along the stabilizer surface such that the depth and the outer surface of the sample flow are stabilized, and the surface fluctuation and depth variation of the stabilized sample slurry flow are reduced. As laser pulses are focused on the outer surface of the planar sample flow to transform at least a part of the sample into a state of a plasma, the accuracy and repeatability of the LIBS measurement are significantly improved due to the stabilized sample flow.

Abstract

Provided is a method of recovering copper and one or more precious metals comprising leaching copper-bearing ore and/or concentrate under atmospheric or slightly pressurized conditions at a temperature below the boiling point of the leach solution in a sulfuric acidic solution in the presence of one or more alkali metal or alkali earth metal halides, whereby the total halide concentration is from 30 to 115 g/L, to dissolve copper and to obtain a leaching liquor comprising copper, sulfur species, and halides in solution. The leaching liquor is then subjected to a solid-liquid separation after which a first aqueous pregnant leach solution and a copper depleted leaching residue are obtained. Copper is purified by solvent extraction from the first aqueous pregnant leach solution to obtain a first copper-containing loaded organic solution and a first aqueous raffinate. The copper containing loaded organic solution is stripped and copper is recovered.
