A scoping study on the Baboto ore body

The Baboto ore body is situated along the same geological structure as the Yalea and the Loulo3 ore bodies. It is located approximately 10km north east of the ROMPAD, 1km north of the village of Baboto. It stretches 5km to the north, a part of the Baboto North ore body lies in the Kofi permit. Relative little sampling has been done; core...

Zinc Removal from Aircraft Aluminium-alloy scrap

This report introduces a method for the removal of zinc from aircraft aluminium-alloy scrap. The driving force for this research is the demand from the secondary aluminium industry for a low zinc content in the Al-alloy scrap, and the growing demand for aluminium in the world. Meanwhile large amounts of obsolete aircraft are stored because of...

Applicability of near-infrared spectroscopy for sensor based sorting of mill pebbles from the Los Bronces copper mine, Chile

Los Bronces is an open pit mine located on a large porphyry copper-molybdenum deposit near Santiago, Chile. Annual production is around 240 000 tonnes of copper and 2 700 tonnes of molybdenum. The extracted ore has a relatively low average copper grade of around 0.6%. This results in relatively high processing costs and creates the need to...

Hot metal quality in the hearth of an iron making blast furnace

After fifteen years of service, blast furnace #7 at IJmuiden’s Tata Steel operation was blown down on the 31st of August in 2006 for a small repair. The blow down and salamander tap were successfully completed and afterwards the furnace was quenched with water. All remaining liquids are solidified followed by excavation of the remaining skull....

Optimization of mining and processing for an Albanian nickel-laterite mine

The scope of the project was to re-evaluate, optimize and update an existing pre-feasibility study of a nickel-laterite project in south-eastern Albania. This included, but was not limited to, the development of the resource estimate; geotechnical assessment of the different rock zones; investigation of potential mining methods; design and...

An optimised iron ore grinding strategy based on balling fundamentals

In order to meet the future demand of pellets for the blast furnace, the output of the grinding circuit of the Tata Steel IJmuiden pellet plant needs to be increased. As the power consumption of the grinding circuit is already at its maximum, the grinding itself and/or the grinding strategy needs to be optimised, leading to a higher circuit...

The root causes of Stope Slippage at Kidd Mine, Canada

Kidd Mine has a production target of 2.5 million tonnes of ore per year in 2010. Seventy-five stopes are turned over to the next stope in order to achieve this annual production. Each turnover from stope to stope has an anticipated number of days based on the geomechanical relation between them. Due to the depth and size of the operation, it is...

Natural Convection Effects on Magnesium Solution Mining

Raw magnesium chloride can be recovered using solution mining at a depth of a 1500 to 2000 meters. Underground caverns are formed in stacked layers of bischofite , carnallite and halite. The salt layers consist for a large part of NaCl and but contain a minimum of at least 35% magnesium chloride. Recovery is implemented by injection of fresh...

Ferrovanadium production from heavy fuel oil fly ash and BOF dust

Vanadium is an important industrial metal that is mostly used as an alloying element in steel and to a lesser extent in titanium. It is generally produced in combination with other metals such as iron, titanium, and uranium. The typical production method begins with salt roasting of the ore or concentrate to produce a water soluble form of...
