WASHABILITY AND FROTH FLOTATION TESTS OF LAFIA-OBI

The Lafia-Obi coal deposit has been found to be geologically faulty and the minimum estimated cost of mining it per ton was at N87.50 as at 1977 (Taskforce, 1987). Considering the present exchange rate of the Nigeria Naira to the US dollar, the current mining price per ton of Lafia-Obi coal can be taken to be US$87.50 (Adeleke and Onumayi, 2007).

The menace of acid mine drainage: an impending challenge

Acid mine drainage (AMD) is one of the most significant environmental challenges facing the mining industry worldwide. It occurs as a result of natural oxidation of sulphide minerals contained in mining wastes at developmental, operating and closed/decommissioned mine sites. This contamination occurs when moving fresh surface water interacts with the rock through fissures, pores and faults, and...
