effective for small-scale operations. Most bauxite, iron, and copper ore is mined by open pit techniques, lead and zinc ore are principally extracted by underground mining methods, and precious metals, particularly gold and most notably in the USA and Australia, tend to be recovered in recent years from low-grade deposits by surface mining.

Open Pit Mining. Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.

1.1.3.1 Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The

The iron ore is mined mostly from open pit deposits through mining operations and the raw product, “run of mine,” is subjected to mineral processing. Thus, the material is exposed to a series of operations of fragmentation, separation by size, concentration, dewatering, etc., aiming to adequate the chemical, physical, and metallurgical characteristics to meet the demands of ironmaking

Iron Ore Open Pit Mining Process Flow Chart. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining.

From there, the ore is transported to a separate facility for smelting, which is: The process of melting the ore concentrate in a furnace to separate the metal. Then, the ore is poured into molds to make bars of bullion. Closure/Reclamation. Once the ore has been processed and shipped away for sale, the final step of the mining process begins.

Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, open-pit produces harmful pollutants depending on the type of mineral being mined, and the type of mining process being used.

Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.

At the processing plant, the taconite is crushed into very small pieces by rock crushing machines. The crushers keep crushing the rock until it is the size of a marble. The rock is mixed with water and ground in rotating mills until it is as fine as powder. Separation The iron ore is separated from the taconite using magnetism.
