Approximately 18,000 ha of land is currently under mining operations in Goa (Kumar, 2000).The present mining rate of 16–21 million ton of ore, with high ore-over burden ratio of around 1:3, means that there is a need of removal and disposal of 40–50 million m 3 of waste per year. Having exhausted the available area for waste dumps within leasehold area, the …
Hematite is one of the most abundant minerals on Earth's surface and in the shallow crust. It is an iron oxide with a chemical composition of Fe 2 O 3. It is a common rock-forming mineral found in sedimentary, metamorphic, and igneous rocks at locations throughout the world. Hematite is the most important ore of iron.

Iron lathe waste powder has the potential as a raw material in the synthesis of hematite pigments. Hematite pigments have many advantages, one of which is anti-swelling properties that can maintain the dimensions of wood. Hematite pigment synthesis was carried out using the precipitation-sonication method.
