The presence of CO during sodaash activation promoted boron leaching because of the reduction of ironbearing minerals in the ore, whereby iron species within magnetite (Fe3 O 4) and ludwigite ( (Mg,Fe)4 Fe 2 [B 2 O 6 ]O 4) transformed to metallic iron. This facilitated the reaction between B 2 O 3 and soda ash, giving rise to the formation of ...

Saugus Iron Works National Historic Site. The blast furnace was where the smelting process was started. In 1646, the original blast furnace roared to life, lit with a 3000 degree fire that was kept burning 24 hours a day for months at a time. The blast furnace is where bog ore was smelted to create cast iron "pig" bars, so named because liquid ...

1. Introduction. Nowadays, with the increasing depletion of high grade and coarsegrained ores, the trend is towards the extraction of lowgrade ores [1].This can have two consequences for the minerals industry; first to process larger tonnages of mineral raw material and second to grind the raw materials to finer sizes [2], which in turn leads to higher energy consumption.
