The maximum height of the stopes, in a single lift from sublevel to sublevel, would be approximately from 15 to 20 metres. Final stope heights in some cases would triple the single lift. Loading of the broken ore onto the trucks would be done with LHD machines. The trucks would haul the ore via the decline up to the surface to the ore storage pile.
Dec 23, 2018018332For example Chesapeake Minerals’ Metates project in Mexico is considered one of the largest goldsilverzinc reserves in the world, at 18.5 million ounces of proven and probable gold.
If ore and waste are only identifiable at the scale of small individual particles, sensorbased bulk sorting will be ineffective and particle ore sorting may be more suitable. Sensorbased particle sorting may be considered for ore types where liberation of mineralized and unmineralized particles can be achieved at particle sizes between 8 mm ...
The mining basin is comprised of a huge hypogenic mass running NW to SE. Its southern edge is in contact with a more recent formation which is the base of the coal deposit. In this basin, coal sediments are broken down into three groups base gaps, production face and ceiling conglomerates.

Ore is natural rock or sediment that contains one or more valuable minerals, typically metals, that can be mined, treated and sold at a profit.Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals.. The grade of ore refers to the concentration of the desired material it contains.

The ore is fed into a 600 tonne capacity coarse ore bin after passing through an 8 inch screen. Ore from the bin is fed to the crushing circuit by two 24 inch by 18 inch reciprocating feeders that discharge onto separate 36 inches wide by 50.6 feet long conveyors, which both discharge onto one conveyor of 36 inches wide by 85.3 feet long.

The Mining sector covers the extraction and processing of metal and mineral ores and deposits, including coal, copper, iron, limestone, nickel, precious metals, potash, uranium, diamonds, minerals, rare earth elements and much more.
A mining method for narrow orebodies where no backfill is required during the stoping operation. Successive horizontal slices of ore are taken along the length of the stope back and left in place to support the walls rocks and serves as a working floor for the next slice. Ore is drawn from drawpoints at the bottom of the mine.
Plumbum ore is common in South Africa, and it is one of the earliest metals which were extracted from leadzinc ore by humans, which hardness is 1.5, melting point is 327.4 ℃, boiling point is1750 ℃.Because of good ductility, plumbum is can be easy made of alloy with other metals such as zinc, tin, antimony, arsenic, etc.

The selected mining method is based on a common surface mining method, open pit benching. The process of mining is the same as terrestrial mines to expose mineralised material, achieve fragmentation, load and haul. Fragmentation at Solwara 1 will be achieved by mechanical cutting rather than drillandblast.
Silver processing, preparation of the ore for use in various products..
