The concentrate produced from the Adirondack magnetites is, of course, too fine for direct use in a blast furnace and must be agglomerated before it can be considered a blast furnace ore. The four operations in the area use sintering -three, including the Jones & Laughlin operation, employing the Dwight Lloyd continuous type machine and one operation using the Greenawalt batch type process. Each operation uses fine anthracite coal, either No. 4 or No. 5 buckwheat size, for the mix fuel.
