The Eco-friendly methods have become a promising synthetic strategy in science and technology in recent years. The current study describes alkaline roasting of chromite ore using Seidlitzia Rosmarinus (S. Rosmarinus) ash and water leaching of resulting cake. The Formation of Na₂CrO₄ was confirmed by Existing of ligand to metal charge transfer (LMCT) band in the UV-visible spectrum in 270 and 370 nm. Rhombohedral structure of the product was investigated using the powder X-ray diffraction (PXRD). The X-ray Fluorescence Spectroscopy (XRF) shows Increasing in chromium percent from 44.94 to 65.07 and existing elementals as sodium, potassium, calcium and magnesium in S. Rosmarinus ash that can act as alkaline assistance in alkaline roasting.
