The results corroborate that when the grinding time of cassiterite is 4 min and the grinding time of sulfide ore is 8 min, the grinding qualified size range index under unit energy consumption is the largest. Cassiterite is brittle and easy to grind due to low hardness, while sulfide is difficult to grind due to high hardness.

Contents of all other elements of concern are very low. The Finnish ore, Hannukainen, is different. Contrary to the Swedish ores, cobbing is not feasible, but the content of Cu in the form of chalcopyrite adds to the value of the ore. The grinding must not be as fine as for the Swedish ores to reach a concentrate grade of the same level, though.
An ore deposit is a well-defined mineral deposit that has been tested and found to be of sufficient size, grade, and accessibility to be extracted (i.e. mined) and processed at a profit at a specific time. Thus, the size and grade of an ore deposit changes as the economic conditions change. Ore refers to industrial minerals as well as metals.
