Solid Wastes Recycling Through Sinter -Status at Tata Steel

摘要

Integrated steel plants generate several by-products rich in iron, flux and fuel values, categorised as waste. These by-products contain, besides mineral values, hazardous constituents causing damages to the environment. The environmental quality consciousness, the product cost competitiveness and the high mineral values of these wastes have resulted in attempts to recycle these materials. Recycling recovers the mineral values, preserves the decreasing natural resources and deteriorating environment and eliminates the disposal cost. Sinter plant provides an avenue for recycling of these wastes. Recycling decreases the cost of sinter and hence the cost of steel produced. Present paper outlines the status of waste generation, their characteristics, and the quantity being recycled via the sinter plant at Tata Steel. Furthermore, it highlights the problems, which restricts its further recycling and discusses its influence on cost and quality of sinter.
