In only one instance in the district, namely, at the Zinc Corporation, is the system of skips with ore pockets below the plats used. It is found generally more convenient, in view of the moderate tonnages hoisted at individual main shafts, to use cages, which are then always available for use in hoisting and lowering men, horses, and material as well as the ore trucks.

method for zinc ore extraction

Ore is natural rock or sediment that contains desirable minerals, typically metals, that can be extracted from it.[1] Ore is extracted from the earth through mining and refined, often via smelting, to extract the valuable element or elements. The grade of ore refers to the concentration of the desired material it contains. The value of the ...
