Surface mining planning and design of open pit mining

09/01/2016Although the basic concept of an open pit is quite simple, the planning required to develop a large deposit for surface mining is a very complex and costly undertaking. At one mine, it may be desirable to plan for blending variations in the ore so as to maintain, as nearly as possible, a uniform feed to the mill. At another operation it may be desirable to completely separate two kinds of ore

Mining Methods and Equipment

In recent years, a number of mining companies have turned to continuous mining systems. This include FMG in the Pilbara, where continuous mining machines having rotating drums fitted with picks are used to mine iron ore, and BMA and Rio Tinto in the Bowen Basin where in-pit-crusher conveyors are used to transport overburden.

Mining and Refining

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.

Open Pit Mining Techniques

People in few of the English-speaking countries are not likely to make a difference among an open-pit mine and other kinds of open-cast mines, like quarries, borrows, placers, and strip mines. Open-pit mines are characteristically engorged until either the mineral resource is exhausted, or a mounting ratio of overburden to ore makes more mining uneconomic.

Iron Ore Smelting Process

Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter. Here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron.
