CHAPTER 8: NOISE AND NOISE REDUCTION TECHNIQUES

CHAPTER 8: NOISE AND NOISE REDUCTION TECHNIQUES 1. NOISE SOURCES Noise can be characterized as any disturbance that tends to obscure a desired signal. Noise can be generated within a circuit or picked up from external natural or artificial sources. When noise is generated within a circuit, it is called intrinsic noise.

The processing of hard rock sulphidic bearing ores is just one example of accelerated weathering. In this case the sulphide minerals more readily oxidise in the tailings facility as a result of the size reduction from milling increasing the surface area and thus exposure of the tailings to air and water.

Mineral processing - Wikipedia

In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition. Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding. The primarily used equipment in crushing are-jaw crushers, gyratory crushers and cone crushers whereas ...

Crusher - Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Ore processing – Waihi Gold

The trash screen (10) removes wood from the old mine workings that may have found its way into the processing circuit. The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand).
