Beneficiation of a phosphoriferous iron ore by agglomeration methods. Int. J. Miner. Process., 1: 231--241. The Snake River iron ore deposit, in the northern Yukon, Canada, is an enormous, potentially valuable natural resource. Conservative estimates indicate that the deposit contains some thirty thousand million tons of ore.
ABSTRACT Sintering is an agglomeration process that fuses iron ore fines, fluxes, recycled products, slag-forming elements and coke. The purpose of sintering is to obtain a product with suitable composition, quality and granulometry to be used as burden material in the blast furnace. This process is widely studied and researched in the iron …

World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.
This book focuses on agglomeration, or the size enlargement process, of iron ores. This process sits at the interface of mineral processing and extractive metallurgy. The book begins with a discussion of raw materials preparation and the beneficiation process.
