Exseer Mining

Exseer Mining  :  Company is a private company founded in 2012 by business  shareholders. It has awarded and  signed in  September 2012, a sharing  contract to develop a suitable technique to collect all scattered artisanal tailings within Abu Hamad area in the River Nile State in Sudan, and to select a suitable metallurgical process to extract the  remaining gold out of them.

The project area is situated in the River Nile State of the Sudan, about 12 km north of Abu Hamad Town (about 550 km from Khartoum) on the eastern bank of the River Nile {N 33◦ 16ꞌ 56⸗ E 19◦ 10 ꞌ 3⸗} (Fig. 2.1). Access to the
plant area is via Khartoum –Abu Hamad asphalt road and then by a north east leveled road to the site. in the proper plant area

The plant entails the reprocessing of artisanal gold mining tailings via heap leach and CIC and mill and CIL. The tailings are stacked and piled into heaps and first agglomerated with cement to improve solution infiltration down the heap. A weak cyanide solution is fed using drip feeders to the heap allowing the gold to dissolve into the cyanide solution. The gold-cyanide leachant ("pregnant solution") is collected into ponds as it percolates out from the base of the heap and then transported to a recovery plan. The gold leached in the pregnant solution is adsorbed on activated carbon, desorbed, refined and stripped in electrowining cells on steel cathodes, followed by smelting scrap.
