The chemical composition of mineral Cobaltlotharmeyerite is indicated by the formula Ca(Co,Fe,Ni)2(AsO4)2(OH,H2O)2. Cobaltlotharmeyerite is also considered as a secondary phosphate mineral in cobalt and nickel-bearing ore dumps. Mineral Cobaltlotharmeyerite is also known as a member of Tsumcorite group. Mineral Cobaltlotharmeyerite is usually found on dump material from the mining area “Am RotenBerg,” approximately 4.8 km SW of the center of Schneeberg, Saxony, Germay. This mineral was named as the cobalt dominant analogue of lotharmeyerite. Mineral Cobaltlotharmeyerite is known to crystallize in the monoclinic system of crystal formation. In optical mineralogy, the monoclinic system of crystal formation comprises crystals having three axes of unequal lengths. Two of which are usually found in a position that is oblique or not perpendicular to one another. However, both of which are commonly found perpendicular to the third axis. There is no cleavage found when mineral was closely evaluated between crossed nicols of polarizing microscope for mineralogists. Mineral Cobaltlotharmeyerite is also found colored brown in hand sample. Most crystals of mineral Cobaltlotharmeyerite are found translucent in appearance. The crystal habit of mineral Cobaltlotharmeyerite as described in the field of optical mineralogy usually includes aggregates that are made up of numerous individual crystals or clusters. Mineral Cobaltlotharmeyerite is usually found fan shaped. It is occurring as radiating crystals shaped like a fan. Sometimes it can be found in lath -shaped like a small, thin plaster lath, tabular or rectangular in shape. The hardness measure of mineral Cobaltlotharmeyerite is usually found 4.5 when measure using the Mohs scale method. Mineral Cobaltlotharmeyerite is usually found exhibiting vitreous to adamantine luster when evaluated in reflected light of polarizing microscopes. Mineral Cobaltlotharmeyerite is commonly found leaving a light brown streak when rubbed on white porcelain streak plate. Mineral Cobaltlotharmeyerite is commonly found showing biaxial positive figure with 0.0700 birefringence exhibited when viewed between crossed nicols of polarizing microscopes. Mineral Cobaltlotharmeyerite is also found showing distinct dispersion. Mineral Cobaltlotharmeyerite is also found not radioactive.
