The episode of COVID-19 poses various challenges that include diagnosis, prevention and proper medication. Hence, most national governments across the globe have advised to accelerate the advancement of biomaterials and techniques for the development of effective diagnosis, therapeutics and control of COVID-19. This study endeavors to give a point of view on how the improvement of novel materials can assist researchers with handling the difficulties with COVID-19 and mitigate the challenges.

Characterization has become an integral part of mineral processing and beneficiation depends on the nature of the gangue present and its association with the ore. Different characterization aspects like mineralogy, textural relationship, liberation size, chemical analysis and grain size analysis are studied to develop the beneficiation As reflected in the National Steel Policy, Hematite iron ore availability in the country will not last long. In order to ensure longer period of ore availability, it is very important that we should plan to use low grade BHQ & BHJ iron ores after beneficiation. Looking at the present scenario IBM has slashed the threshold value of 45% Fe(T). According to National mineral policy projections, exploitation of the low grade iron ore horizons like BHJ, BHQ, and BIF etc. is necessary to achieve zero waste mining. BHJ assaying up to 40% Fe(T) has to be upgraded above 60% Fe(T) to use effectively It may also be noted that attaining liberation may be an extremely difficult job requiring comminution down to about a few microns. Technically it is possible to enhance the quality of low grade as well as BHQ/ B HJ iron ores to an acceptable grade using various techniques like Flotation, Enhanced gravity separation, WHIMS etc.

The ratio of lumps to fines produced in the country is 2:3. During washing and sizing of the ore, slimes with less than 0.21 mm size are generated and discarded into the tailing pond. It is estimated that around 10 million tons of slimes are being generated in every year during the processing of hematite ore and lost as tailings containing around 48-62 % of Fe. The slime sample collected from Barsua assaying 54 % Fe, 8.3 % SiO2 & 11.08 % Al2O3 was studied for pre concentration of iron values adopting gravity techniques followed by magnetic separation. The results indicated that Magnetic separation is a better pre concentration technique compared to gravity.

The limestone rock samples were collected from the study area for testing purposes. The geomechanical parameters like compressive strength, axial strain, young’s modulus, cohesive strength, angle of internal friction, etc., were experimentally determined to study their application in the simulation of slope failure analysis. A 2D model of the study area was developed using the field data for modelling and simulation purposes. Slope failure analysis was carried out using the Finite element method (FEM). Results indicated maximum compressive strength of the core sample as 85.14 MPa while axial strain and elastic modulus were 0.02197 and 842.45 MPa, respectively. The cohesive strength and the angle of internal friction of the core sample were evaluated as 38.59 kPa and 12.96 degree. The slope failure analysis was ...
