The previous project had been able to produce manganese sulfate with a purity exceeding 99.6% and low levels of base and alkali metals using material from Battery Hill property which comprises of rhodochrosite, a manganese carbonate mineral
. The company's preliminary flow sheet utilized specific parameters for Battery Hill ore and yielded very encouraging results.
The project involves injecting carbon dioxide into processed kimberlite rock in order to accelerate the naturally occurring process of mineral carbonation, whereby processed mine rock (material left after the recovery of diamond from source rock, kimberlite) sequesters the carbon dioxide as a stable and benign carbonate mineral
. The research offers great opportunity as the carbon storage capabilities of kimberlite processed while mining is such that only 10 per cent of the rock's storage potential would need to be harnessed to capture the carbon dioxide emissions of a whole mine.
[USPRwire, Fri Sep 28 2018] Nyerereite is a highly rare form of sodium calcium carbonate mineral
with formula Na2Ca(CO3)2.
The carbonate mineral
content ranges from 15.6% to 62.0%(average 32.2%), the clay mineral content ranges from 14.1% to37.2%(average 28.1%), and the quartz contentranges from 15.3% to 41.7%(average28.3%).
Table 2 presents the chemical composition of the spring water obtained at points I-III, along with the degree of saturation with respect to each carbonate mineral
, log [OMEGA] ([OMEGA] = Q/[K.sub.eq]).
inclusions such as calcite and dolomite were documented in trapiche ruby arms by Schmetzer et al.
Loss on ignition: a qualitative or quantitative method for organic matter and carbonate mineral
content in sediments?, Journal of Paleolimnology 32(3): 287-299.
A Raman map of the polished surface shows calcite to be the only carbonate mineral
present, however, there are two interesting features of the map that provide further information.
As such, it is of interest to study if NiNP can have an influence on the carbonate mineral
phases formed, besides affecting the reaction kinetics.
Shells composed of a carbonate mineral
called aragonite (such as the pteropod pictured above) are particularly sensitive to the decreasing pH levels in the water.
Despite being labeled a cloak, it's actually a box - two pieces of calcite, a natural carbonate mineral
that can bend light and suppress shadows around objects, pieced together.
