1.1.5 Ore extraction After a mining company has removed overburden, extraction of the mineral ore begins using specialized heavy equipment and machinery, such as loaders, haulers, and dump trucks, which transport the ore to processing facilities using haul roads. This activity creates a unique set of environmental impacts, such as emissions of
· This oversized material can damage downstream equipment and is therefore removed from the slurry. Surge capacity: Although mines operate 24/7, mining is a batch process susceptible to brief outages. Supply disruptions can occur when shovels are being relocated, during shift change and especially in spring when ground conditions are very soft.
· In 1914 a contract was let for removing 8,000,000 cubic yards of stripping at the rate of 2,000,000 cubic yards per year to uncover 6,000,000 tons of ore for open-pit mining. It was contemplated that later work would require the additional removal of 14,000,000 cubic yards of overburden to make available for mining an additional 19,000,000 tons ...

· Special Report: Declining iron ore grades globally and the rising demand from steelmakers for higher grade product is creating the perfect storm for explorers with the goods. In Australia, hematite has been the dominant iron ore mined since the early 1960s, accounting for about 96 per cent of the country''s iron ore exports.
copper mining industry has virtually disappeared within the last 40 years due to the effects of depletion and the rising cost of labour- intensive mining from rich but deep and inaccessible ores. The decline in average grade appears together with a decrease in the variance of the grade of ore mined.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
