Sayak Sarkar

I specialize in chemical and physical testing of minerals and coal, including dolomite, limestone, bauxite, ferro alloys, iron ore, and more. With hands-on experience in coal proximate analysis, GCV, and elemental determination (sulphur, phosphorus, alumina), I ensure accurate and reliable laboratory results through strict adherence to ISO 17025 standards. I am skilled in standard solution preparation, wet analysis laboratory equipment calibration, and quality control processes, and I consistently maintain compliance with SOPs and QA/QC protocols.

My work supports precise material characterization, contributing to high-quality outcomes for ferro and non-ferro minerals.
