Mr Bujtor stated, "The quality of the coal extracted in the Philippines is poor, but a lot of this coal is sold domestically to power stations. In the RKF (rotary kiln furnace) process to produce NPI, this coal is certainly good enough for ore drying." "You don't need high quality coal for ore drying in a rotary kiln.

With no special preparation of the ore fines, a rotary kiln is able to handle ores with a larger proportion of fines than a shaft furnace or traveling grate. Ore containing, up to 10 percent of -325 mesh requires no special preparation before feeding to the kiln. Although the outcome of roasting even finer ores can not' be accurately ...

The oxidizing roasting cinder—containing 16.9% Pb, 30.5% Zn, 10.3% Fe and 25.1% S—was obtained from a Pb-Zn sulfide ore in the Hanyuan area of China by a flotation-rotary kiln oxidizing ...

This paper summarizes more than a decade of systematic studies of the flow field in an iron ore pelletizing rotary kiln using computational fluid dynamics (CFD) on simplified models of a real kiln. Physical, laser-based experiments have been performed to validate part of the numerical results. The objective is a better understanding of the kiln aerodynamics and, by …

22 Philippine Metals, Vol. 1, 2014 Technical Study for the Value Adding of Philippine Iron Ore Resources Abstract This paper examines the value adding of local iron ores in order to obtain maximum benefit from Philippine mineral re-sources. Ironmaking operations in the Philippines during the Spanish and American colonization era were reported and

The Philippines is rich in iron ore, particularly in the form of magnetite sand, and exports them after mini-mal value adding operations. Based on the Metallic Resource/Reserve Inventory of …
