Particle Analysis in Mining and Minerals

Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.

During this phase, the ore is extracted, processed, and refined to produce metal. This section forms the bulk of the focus of the financial model for an operating mine. Once all the ore has been extracted, the mine closure process begins, which can last for several years. The process includes clean-up, reclamation, and environmental monitoring.

Mining and Refining – Process

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.

Life Cycle of a Mine

Once removed, the ore is transported for processing using large haul trucks. Milling. Regardless of the deposit type and mining process, ore must be separated from the waste rock once it has been removed from the ground. The minerals are removed from the ore by using one or more methods, and this separation is usually done in a mill.
