Economic use of galena.

In this study, the leaching kinetics of galena by ferric methanesulfonate is undertaken. Ferric ion, compared to hydrogen peroxide and oxygen, is more economic in use. The chemistry of galena leaching with ferric methanesulfonate is as follows. Elemental sulfur may be further oxidized to sulfate (SO 4− 2) which precipitates lead (Pb + 2) to ...Definition time. Any mineral that has economic potential (i.e., it makes someone money), is defined as an economic mineral. All of the minerals listed in table 1.5 are economic minerals. Additional economic minerals include the native elements Gold, Silver and Platinum, virtually every sulfide known (e.g., Molybdenite-MoS, cinnabar-HgS etc.),In the separation of mixed sulphide minerals, pyrite often remains in the valuable concentrates, reducing their grade and economic value. Simultaneously, sulphur dioxide is readily released causing acid rain. Importantly, pyrite is often associated with galena, sphalerite and other valuable sulphide minerals.Figure 3.5.5 3.5. 5: Limonite, hydrated oxide of iron. After carbonates, the next most common non-silicate minerals are the oxides, halides, and sulfides. Oxides consist of metal ions covalently bonded with oxygen. The most familiar oxide is rust, which is a combination of iron oxides (Fe 2 O 3) and hydrated oxides.Definition time.
