Surface mining, wherever applicable, is more advantageous than underground mining in terms of ore recovery, operational flexibility, productivity, safety, and cost. Currently, almost all nonmetallic minerals (more than 95 percent), most metallic ores (more than 90 percent), and a large fraction of coal (more than 60 percent) are mined by surface methods (Hartman, 1987). However, as surface mineral deposits are exhausted, underground mining will inevitably become more prevalent. In addition, as more easily minable deposits are depleted, mining technology and equipment and mining systems for extracting problematic deposits will have to be developed

For many decades the two-compartment ball mill in closed circuit with a high-efficiency separator has been the mill of choice. In the last decade vertical mills have taken an increasing share of the cement milling market, not least because the specific power consumption of vertical mills is about 30% less than that of ball mills and for finely ground cement less still. The vertical mill has a proven track record in grinding blastfurnace slag, where it has the additional advantage of being a much more effective drier of wet feedstock than a ball mill

Before all that iron ore can be turned into steel, it must go through the sintering process,which is the step between mining iron ore and steelmaking. The U.S. Environmental Protection Agency explains that thesintering processconverts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace

Another incinerator that was originally used for sludge incineration is the fluidized bed incinerator. This system utilizes a fluidized sand bed as a heat reservoir to promote uniform combustion of algal solids. The fluidized bed is preheated, using fuel oil or gas, before the algal slurry is introduced. The dried algae are separated from the sand by a cyclone separator [36]
