how is sulphide ore and iron ore concentrated
Answers
Answer:
Sulphide ore are concentrated by froth flotation process because pine oil selectively wets the sulphide ore and hence brings in to the forth .
&
Iron ore concentrated before putting it into blast furnace . Firstly by washing with water, clay and sand impurities removed thus ore become concentrated . Then calcination is a process which involves heating up the ore with excess air to remove the gasious impurities.

Answer:
Another method of concentration of ores is the Froth Flotation Method. This is the process for concentration of primarily sulphide ores. It has the advantage over gravity separation because it can collect even the extremely fine particles of minerals. ... Minerals are generally wetted by oil and gangue is wetted by water.
