Slag - Wikipedia

Slag is the collection of compounds that are removed. In many smelting processes, oxides are introduced to control the slag chemistry, assisting in the removal of impurities and protecting the furnace refractory lining from excessive wear. In this case, the slag is termed synthetic.

Why phosphorous is important - dpi.nsw.gov.au

Crushed rock phosphate is sometimes used as a fertiliser but is very insoluble. Reactive phosphate rock (RPR) can be more soluble than crushed rock phosphate where there is acid soil and high rainfall, such as occurs on the North Coast. Manure All manures contain phosphorus, and manure from grain-fed animals is a particularly good source.

Blast furnace - Wikipedia

At Laskill, an outstation of Rievaulx Abbey and the only medieval blast furnace so far identified in Britain, the slag produced was low in iron content. Slag from other furnaces of the time contained a substantial concentration of iron, whereas Laskill is believed to have produced cast iron quite efficiently.
