Raw material consumption patterns at West Bokaro and Jharia Collieries are given in Fig.5.4 and Fig.5.5 respectively. Reduction in ash content to <15% in West Bokaro coal had a favourable impact in containing specific raw material consumption.

Raw material consumption and Production of Ferro Manganese and Ferro Chrome from FAMD is indicated in Table 5.2.

The Tubes Division used steel supplied from Steel Works. The scrap generated from this Unit is recycled to Steel Works. Even though Tata Steel is vertically integrated, materials consumed in mining operation have not been considered here. Similarly, other consumables and spares used in the mining operations have also not been included.

Fig.5.6 indicates the cascade use of lubricants and recycle of waste oils for energy recovery at Sukinda Mines.
