May 01, 2020  Low grade dumped limestone sample having high silica of 8.1%, 36.8% CaO, and 3% Al 2 O 3 has been studied with the aim to reduce the silica level to below 3% for its utilization in iron making. Beneficiation study of the sample was initiated with desliming of the feed sample of −100 µm to remove the siliceous ultrafine particles and to improve the feed quality.

Insights into the desulfurization mechanism of low-grade ...

However, few studies have focused on the low-grade limestone which interestingly contains the impurity CaMg(CO 3) 2 formed due to the dolomitization of calcite . Besides, the large consumption of high-grade limestone will definitely lead to the decrease in limestone grade and thereby the surplus of low-grade limestone in the near future.

Nov 11, 2020  However, low-grade limestone with CaCO 3 purity of less than 94% contains impurities such as MgCO 3, Al 2 O 3, and SiO 2, which reduce gypsum purity. To resolve this issue, a process involving mixing of both low-grade and high-grade limestone was simulated to predict the quantity of low-grade limestone that could be utilized.

During the extraction of limestone in quarries, so-called pre-screening debris are generated. Up to 90 % of this pre-screened material consists of good limestone rock, which is frequently heavily interstratified with clay and loam impurities. Therefore, it could only be sold as a low-grade product without being correspondingly cleaned.
