pulp of iron ore
Iron Ore
Iron Ore. Oolitic iron ores are a distinctive subset of iron ore deposits, and are characterised by their spherical grains composed of concentric layers containing hematite and goethite along with impurity elements such as silicon and phosphorus. ... The pulp is subjected to hydrocyclones for separation of slimes and removal of silica ...

Gold Ore Roasting Techniques
The first stage is in the preliming agitator, where the pulp is given a thorough aeration. This aeration oxidizes the ferrous iron in the pulp to the ferric condition, in which form iron has a negligible cyanide consumption and no oxygen consumption. It also serves to saturate the pulp with oxygen before any cyanide is added.

The proportion of iron is 100 — (34.8 + 34.8) = 30.4%. Roughly, the ore may be considered as composed of one-third each of copper, sulphur, and iron. This is the commonest ore of copper; but its value depends so much on circumstances other than the percentage of copper contained in it that it is not quoted on the market.
