However, this spoil has lead to some new mining methods being developed. Phytomining is a method of extracting metals from low grade ore and spoil. Metal tolerant plants are deliberately grown on mining waste then harvested and a new crop planted. The harvested plants are treated and the metals extracted.

Extracting iron from iron ore using a Blast Furnace.
In ancient times, iron had to be reheated and hammered into shape. Also, hammering was the only way to get rid of the impurities that made bloom iron so brittle. Hammering closed up the pores in the iron bloom and welded them shut.
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.
Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice. This also applies to iron ores of the nonmagnetic type which after a reducing roast are amenable to magnetic separation.
Iron ore mining methods vary by the type of ore being mined. There are four main types of iron ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits.
Abstract. The deep mining of iron ore is unusual in the modern era, but in northern Sweden, ore is mined from considerable depth largely aided by the application of automation and remote control equipment. Kiruna has been chosen as the example for a more detailed review of underground techniques.
Most early American ironworks extracted the iron ore from "bog iron" deposits large nodules of quite pure iron that forms along the roots of plants in boggy areas. Bog iron could be easily scooped up from the mucky bottom with longhandled rakes into flatbottomed boats and then dried on shore.
The method. Three substances are needed to enable to extraction of iron from its ore. The combined mixture is called the charge: Iron ore, haematite often contains sand with iron oxide, Fe2O3. Limestone (calcium carbonate). Coke mainly carbon. The charge is placed a giant chimney called a blast furnace.
Phytomining is a method of extracting metals from low grade ore and spoil. Metal tolerant plants are deliberately grown on mining waste then harvested and a new crop planted. The harvested plants are treated and the metals extracted.
