The Pyroxenite Market value for was USD 104.54 Million in 2022 and is expected to reach USD 170.37 Million in 2032 growing at a CAGR of 4.54% during the forecast period. Pyroxene, olivine, and chromite are the main minerals in pyroxenite, a form of ultramafic rock. Pyroxenite is increasingly in demand due to factors including its application in creating premium Steel and the rising demand for infrastructure development projects.
