With the exception for some deposits that are logistically challenged, iron ore resources in more accessible areas may often have processing issues, especially if high-grade concentrates are desired. This paper addresses some of these with examples on how …
Read MoreThe high iron content of the sphalerites in the gold ore deposits in the Săsar area could be formed at high f S 2 which explains the lack of tellurium and the presence of native gold. If the temperature remains relatively constant, the boiling of the fluid will lead to loss of sulfur gas, meaning a decrease in f S 2 .

Read MoreHowever, there is a significant incentive for studying the operation of spiral concentrators. Indeed, iron ore plants usually process on a daily basis more than 100,000 t [1] of ore through spirals. For such throughput, a 0.5% improvement in the recovery of iron minerals can yield additional revenues of several hundred thousand dollars per year.
