Geochemistry, Mineralogy and Microbiology of Cobalt in Mining-Affected Environments
minerals Article Geochemistry, Mineralogy and Microbiology of Cobalt in Mining-Affected Environments Gabriel Ziwa 1,2,*, Rich Crane 1,2 and Karen A. Hudson-Edwards 1,2 1 Environment and Sustainability Institute, University of Exeter, Penryn TR10 9FE, UK; [email protected] (R.C.); [email protected] (K.A.H.-E.) 2 Camborne School of Mines, University of Exeter, Penryn TR10 9FE, UK * Correspondence: [email protected] Abstract: Cobalt is recognised by the European Commission as a “Critical Raw Material” due to its irreplaceable functionality in many types of modern technology, combined with its current high-risk status associated with its supply. Despite such importance, there remain major knowledge gaps with regard to the geochemistry, mineralogy, and microbiology of cobalt-bearing environments, particu- larly those associated with ore deposits and subsequent mining operations. In such environments, high concentrations of Co (up to 34,400 mg/L in mine water, 14,165 mg/kg in tailings, 21,134 mg/kg in soils, and 18,434 mg/kg in stream sediments) have been documented. Co is contained in ore and mine waste in a wide variety of primary (e.g., cobaltite, carrolite, and erythrite) and secondary (e.g., erythrite, heterogenite) minerals. When exposed to low pH conditions, a number of such minerals are 2+ known to undergo dissolution, typically forming Co (aq). At circumneutral pH, such aqueous Co can then become immobilised by co-precipitation and/or sorption onto Fe and Mn(oxyhydr)oxides. This paper brings together contemporary knowledge on such Co cycling across different mining environments. -

54 SKUTTERUDITE FROX{ COBALT. ONTARIOI on Some Specimens
54 THE AMENICAN M]NENALOGIST SKUTTERUDITE FROX{ COBALT. ONTARIOI T. I/. WALKER Uruiuersily oJ Torontn On somespecimens recently obtained from the Temiskaming mine, Cobalt, Ontario, small brilliant crystals resembling smal- tite were observed,imbedded in fragments of soft chloritic or micaceouscountry rock includedin the vein. As is well known, smaltite and chloanthite closelyresemble one another and are commonlyintergrown in the samecrystal. It was with a view to determiningthe relative purity of the supposedsmaltite that this examinationwas undertaken. The principal ore in the vein is smaltite,usually massive, but occasionallyforming rough crystalsup to b or 6 millimeters in diameter. The rest of the vein matter is either calcite or lrag- ments of country rock. The small crystals under investigation seemto representthe latest mineral to form;they are tirr white, and verSzlustrous. The specific gravity, determined on 0.62 gram of carefully selectedcrystals, is 6.29,which is closerto the value usually given for skutterudite (CoAss) than to that for smaltite (CoAsz). The crystals, which seldom exceed a millimeter in diameter, were measured on a Goldschmidt goniometer. The fol- lowing forms were obseryed on each crystal: a(IOO), o(111), d(110), and n(211). The relative development of the forms is shown in figure 1. Nothing observed suggests that the crystals are Frc.1. hemihedral-the faces of the last two formswere not alwayspresent in full, but the omissionsappeared to be quite irregular. These four forms have all been observed on both smaltite and skutterudite. An analysis made on the powdered mineral is shown in I. l Presented at the firrt annual meeting of the Mineralogical Society of America, December 28, 1920. -

Ores that are generally processed for only a single metal are those of iron, aluminium, chromium, tin, mercury, manganese, tungsten, and some ores of copper. Gold ores may yield only gold, but silver is a common associate. Nickel ores are always associated with cobalt, while lead and zinc always occur together in ores. All other ores are complex yielding a number of metals. before being treated by chemical methods to recover the metals. Ores undergo a beneficiation process by physical methods and grinding then separation of the individual mineral by physical Figure 2: Metals and metalloids obtained from ores.

A Specific Gravity Index for Minerats
A SPECIFICGRAVITY INDEX FOR MINERATS c. A. MURSKyI ern R. M. THOMPSON, Un'fuersityof Bri.ti,sh Col,umb,in,Voncouver, Canad,a This work was undertaken in order to provide a practical, and as far as possible,a complete list of specific gravities of minerals. An accurate speciflc cravity determination can usually be made quickly and this information when combined with other physical properties commonly leads to rapid mineral identification. Early complete but now outdated specific gravity lists are those of Miers given in his mineralogy textbook (1902),and Spencer(M,i,n. Mag.,2!, pp. 382-865,I}ZZ). A more recent list by Hurlbut (Dana's Manuatr of M,i,neral,ogy,LgE2) is incomplete and others are limited to rock forming minerals,Trdger (Tabel,l,enntr-optischen Best'i,mmungd,er geste,i,nsb.ildend,en M,ineral,e, 1952) and Morey (Encycto- ped,iaof Cherni,cal,Technol,ogy, Vol. 12, 19b4). In his mineral identification tables, smith (rd,entifi,cati,onand. qual,itatioe cherai,cal,anal,ys'i,s of mineral,s,second edition, New york, 19bB) groups minerals on the basis of specificgravity but in each of the twelve groups the minerals are listed in order of decreasinghardness. The present work should not be regarded as an index of all known minerals as the specificgravities of many minerals are unknown or known only approximately and are omitted from the current list. The list, in order of increasing specific gravity, includes all minerals without regard to other physical properties or to chemical composition. The designation I or II after the name indicates that the mineral falls in the classesof minerals describedin Dana Systemof M'ineralogyEdition 7, volume I (Native elements, sulphides, oxides, etc.) or II (Halides, carbonates, etc.) (L944 and 1951). -
