  • The Making of Iron & Steel

    Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.

    Miners go underground in shaft cages and then walk or take trains to the work face. The ore undergoes a series of crushing and milling steps to reduce its size for further processing. Gold is leached from the slurry by means of dilute cyanide solution. Gold has a high affinity for cyanide solution.

  • Steps in the Modern Steelmaking Process

    Modern steelmaking can be broken down into six steps: Ironmaking, which is the first step, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. The resulting molten iron, also referred to as hot metal, still contains 4 to 4.5 percent carbon and other impurities that make it brittle.

  • How Is Gold Extracted From Gold Ore? | Sciencing

    In all methods of gold ore refining, the ore is usually washed and filtered at the mine, then sent to the mill. At the mill, the ore is ground into smaller particles with water, then ground again in a ball mill to further pulverize the ore.

  • Uranium processing - Canadian Nuclear Association

    Uranium milling. The first step is to crush the ore and mix it with water so that it can move through a series of mill circuits. After crushing, the ore is treated with acid in large tanks, to separate the uranium from other minerals in the rock. The uranium is now part of a liquid solution, which is then separated from the other minerals,...

  • Gold Smelting Process | Sciencing

    The first step in the gold smelting process occurs when ore containing gold is mined from the earth. At this point, the crude binding matter and the gold metal need to be separated. This is accomplished by pulverizing or crushing the gold ore, and then placing it in a furnace.
