the best type of sampling for iron ore

Ironore mining methods vary by the type of ore being mined There are four main types of ironore deposits worked currently depending on the mineralogy and geology of the ore deposits These are magnetite titanomagnetite massive hematite and pisolitic ironstone deposits

Ore Sampling System A In the same way a 1pound portion as the third cut of the second sample will find its way to the bucket Z2 This series of operations will occur at each revolution of the upper apportioner and at the end of the hour each of the buckets Z1

One 200g subsample is taken for each 125 t to be shipped Consignments of more than 15000 but not more than 60000 t One 200g subsample is taken for each 250 t to be shipped Consignments of more than 60000 t One 200g subsample is taken for each 500 t to be shipped” In order to prevent loss of moisture from the samples between the

Exploitation of existing iron ore deposit is the easier part of the mining operations The harder part is to find new ore deposits and to define their extent and the iron content grade Exploration is the process by which the accumulations of iron ore minerals can be found in the earth’s crust

In the table below is a basic sampling equation that relates particle size to the amount of sample to be taken with constants derrived for varions types of ore bodies The values for M are the sample size required in pounds Tha values of k are the constant derrived for differing ore

Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted Iron ore mining is classified into two categories manual mining and mechanized mining methods Haematite and magnetite are the most commonly found iron ore minerals

The two main methods of recycling iron from iron ore tailings are magnetizing roasting and direct reduction Magnetizing roasting uses temperatures between 700 and 900 °C for a time of under 1 hour to produce an iron concentrate Fe 3 O 4 to be used for iron smelting

The relative preference for different ore types depends on market conditions and the differentials between the various iron ore indices are very dynamic Perhaps the biggest driver of all is the profit margin that steelmakers are achieving defined by the price at which they sell their steel minus the costs of their raw materials inputs
