The industry includes establishments carrying out activities such as developing mine sites and preparing zinc ores, lead-zinc ores, zinc-blende (sphalerite) ores, zincite ores, and blende (zinc) ores.
As can be seen in the diffractogram for zinc oxide sample (Figure 1(a)), the reflections corresponding to zincite (ZnO) phase are observed.
Several nanomaterials have been shown to have antifungal properties like silver [9, 10], copper [11, 12], zincite [13, 14], titania [15], nickel, and core-shell Ag-Si[O.sub.2] [16].
According to Lindsay (1979), minerals like ZnO (zincite) and ZnC[O.sub.3] (smithsonite) are too soluble to persist in soils.
The major reflections of the samples were indexed to a hexagonal synthetic zincite of the space group, P63mc (186), using the Joint Committee on Powder Diffraction Standards (JCPDS) card number 00005-0664 [24].
In the original sample major peaks of zincite (ZnO), franklinite (ZnFe2O4) and magnetite (Fe3O4) were identified in which ZnO has four distinct peaks with 2th angle of 31.77, 34.42, 36.24 and 47.57 were observed.
The common secondary zinc minerals are smithsonite (ZnC[O.sub.3]), zincite (ZnO), hydrozincite [Z[n.sub.5][(OH).sub.6][(C[O.sub.3]).sub.2], willemite (Z[n.sub.2]Si[O.sub.4]) and hemimorphite [Z[n.sub.4]S[i.sub.2][O.sub.7] [(OH).sub.2] [H.sub.2]O] also known as calamine.
Different phases identified by XRD analysis are zincite, franklinite and magnetite with zincite being dominant.
Coloring by aurichalcite or pseudomalachite inclusions makes crystals opaque, blue or green; crystals may also be colored yellow by (supposedly) zincite, black by sulfides (chalcocite) or red by iron oxides.
LXXXIV, "Zincum oxygenizatum, Oxide of Zinc" or zincite from the Franklin area in New Jersey notes that its discoverer was also Archibald Bruce.
Kudums then exchanged the specimen with Carter Rich for a zincite crystal from Franklin, New Jersey.
