The selection of the adequate mining method is the cornerstone for mine planning and design. This selection depends on geological, geotechnical, economical, and environmental parameters. This paper's main purpose is to select the most appropriate mining method for the south body of Boukhadra underground mine (NE Algeria).
In the 18th century, it was discovered that sphalerite, or zinc sulfide, could be smelted into brass, resulting in the first patented techniques. Since then, the zinc industry has progressed to the current zinc mining process and production methods used today. The Basics of Zinc Mining and Processing
Tin processing, preparation of the ore for use in various products. Tin (Sn) is a relatively soft and ductile metal with a silvery white colour. It has a density of 7.29 grams per cubic centimetre, a low melting point of 231.88 °C (449.38 °F), and a high boiling point of 2,625 °C (4,757 °F). Tin is

Mining method selection by multiple criteria decision making tools by M.R. Bitarafan and M. Ataei* Synopsis Mining method selection is the first and most important problem in mine design. In this selection some of the parameters such as geological and geotechnical properties, economic parameters and geographical factors are involved.
The previous methods of ore selection at most of these operations were based mainly on polygonal - sectional methods of grade estimation. At all of the sites where grade control optimisation has been given a fair trial over several months of production, the use of the MP method has been consistently rewarding to the mining operations.
