Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
from mining tailings and industrial waste, as in the case of the Penouta mine, the CHROMIC project, biohydrometallurgy at the Kasese mining site, and the REDMUD project. Moreover, the aim of the SMART GROUND and CRITICEL projects is to improve the knowledge base on the availability of critical, precious, and valuable secondary materials.

1.5 Data Mining Process: Data Mining is a process of discovering various models, summaries, and derived values from a given collection of data. The general experimental procedure adapted to data-mining problems involves the following steps: 1. State the problem and formulate the hypothesis
From there, the opal bearing material is taken away for processing, either 'wet' puddling or 'dry' puddling. Wet puddling is the process by which the opal dirt is rinsed within an 'Agi' (agitator) to release the opals for the dirt. The Agi is the rear-end of an old cement mixer and is placed somewhere near a water supply/dam.
