Media competency is marginal and the possibility for "critical size" buildup exists; however, ore structure is such that semi-autogenous grinding appears to be a good possibility and pilot plant testing of semi-autogenous grinding is warranted. Further testing is not warranted. Conventional crushing and grinding should be used. a.

Ore is mined and processed at an onsite flotation processing plant capable of treating up to 24 million tonnes per annum (Mtpa). The plant currently recovers copper, gold and silver into a saleable concentrate. The primary ore is crushed and ground using Semi-Autogenous Grinding and Ball mills to a final grain size of approximately 180 microns.
Semi/near-real-time mapping allows upgrading the blending or compositing strategy for the classes to maximise the performance of mineral processing. The sections below provide details on exploiting these requisites and serve as a foundation for understanding how differences in geology impact metallurgical plant performance.
Flowsheet of Portable Ore Processing Plant B. This flowsheet lends itself to a one mineral separation by flotation. The grinding is accomplished by a 30′ x 18″ Convertible Ball Mill with a Spiral Screen at the discharge. The Unit Flotation Cell in the ball-mill-classifier circuit recovers a high percentage of the coarse mineral values.
Textural parameters, such as mineral liberation size and mineral association, combine with modal mineralogy data to strongly influence mineral processing conditions and recovery. Traditionally, the measurement of these ore characteristics employed the tools of an optical microscope and/or a semi-automated SEM.

Gold mineral processing plant. Why Is Mineral Processing Important? The profitability of a mine is based on how much concentrate of the desirable mineral can be extracted from the ore. As a result, mineral processing is designed to yield the maximum amount of mineral concentrate possible before products hit the market.
There is an increasing demand to simulate and optimize the performance and profit of comminution circuits, especially in low-grade ore processing, as is the case with critical metals minerals. Recent research has shown that the optimization result is greatly influenced by quality aspects of the products, such as cost, profit, and capacity. …
