investment and scheduling alternatives, such as equipment sizes and placements, ore definition (cutoff grade determination), ore access mechanics (shaft loion, pit size), and ore and waste removal sequences. The decisions are updated through time, usually annually, as new information becomes available. It is a forwardlooking exercise.
ground: surface mining and underground paper, we will be focusing on the former. Many problems arise in openpit mining: orebody modelling, creation of the lifeofmine (LOM) schedule, determination of mine equipment requirements and optimal operating layout, and the optimal transportation of ore from pit to port. Each

Chlorination is not commonly used to oxidize sulfide ores because of high equipment maintenance costs caused by the corrosive nature of the oxidizing agent.
· Mining activities require machinery and equipment, construction, and other services, which presents the best prospects for companies as their importation is on the rise. Companies with expertise in geological and exploration services, feasibility and engineering services, equipment and plant maintenance and repair, and spare parts for mining equipment can find this subsector .
In the following discussion, the applicability of geophysical methods to geoenvironmental studies of ore deposits is reviewed. Details of geophysical techniques are not emphasized; these are covered in standard texts (Society of Exploration Geophysicists, 1966; 1990) and have been summarized in Hoover and others (1992).
two or more minerals . Ore, for example, is an aggregate containing precious or useful metal along with other minerals that must be separated out before the metal can be used. Three of the samples in your kit are ore samples : iron, copper, and gold.
Mining energy consumption contributes to mining operational costs and occurs at all stages of the ore recovery process: blasting, excavation, crushing, transport and grinding (comminution). For example, the copper mining industry is expected to consume terawatthours (TWh) in 2025, an increase of percent from 2013 [11].

The extent of land degraded during the period between 1988 and 2001 is estimated at hectares ( percent of total area of Gulburga district. In Chitradurga, 90 percent of mining is of iron ore and the balance is lime stone (9 percent) and Manganese (1

Dennis Collection of Stereoscopic Views) In the 1871 pictorial map of Negaunee (below), the open pits of the Jackson Mining Company are visible in the upper left corner. The Cliffs iron furnace is in the lower right corner.
− MineStar Terrain – Iron ore mining requires precision operation of mining equipment for precision excavation. Vehicles used in excavation (diggers, excavators, load ers, etc.) each have GPS that communies loion and helps in guiding excavation accuracy (within 200 mm is needed) to increase productivity and provide
slice. Mining continues upwards towards the surface until the ore body is depleted. Sublevel Caving Sublevel caving is usually carried out when mining of the ore body through an open pit method is no longer economically feasible. Mining now proceeds underground, underneath the open pit. At first, both a raise and a network of tunnels are made.
