### Mineral Formulae Recalculation - SERC

Because electron beam analyses do not differentiate among the valence states of iron (iron is normally reported as FeO), the formula calculation procedure may be different for different iron-bearing minerals. For some minerals (pyroxenes, olivine), by making the assumption that all the cation-sites are full and the mineral has perfect charge balance, the proportion of the Fe that is Fe ...

In physics, yield stress refers to the stress level at which the material tend to behave elastically. The point at which the stress occurs is called as yield point. The stress divided by the strain is no longer constant because the material will deform to its original position when the applied stress is removed. You can use this yield stress formula to find the yield stress of any material or ...

The theoretical yield is what you calculate when you do a calculation on paper or before you do a reaction in a lab. The actual yield will always be less than the theoretical yield because no chemical reaction ever reaches 100 percent completion. In a lab setting, there's always some amount of error, whether it's big or small.

A yield loss arises in any parts of the iron and steel making process, when for a particular step, the weight of the steel product made is less than the input of steel that is used. In a cold rolling mill for example, if the input - often called a charge weight - is 100 tonnes of hot rolled coil, and the output is 95 tonnes of cold-rolled steel, the yield performance equals 95%. Another way of ...
