Mining Sector Profile Uganda Investment Authority
Uses: The commonest use of gold is in gold bullion, followed by jewelry and electronics especially in the computer industry. Iron Ore: Iron ore occurs principally as two types of minerals: hematite and magnetite. Hematite of high quality (90-98% Fe2O3) occurs at Butare in Kabale district; Kashenyi, Kyanyamuzinda and Kamena in Kisoro district with total resources in excess of 50 million tons,

Iron ore extraction techniques ScienceDirect
Jan 01, 2015 Iron ore was won by drilling and blasting ().As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as “dogger”) allowing mine drivages to be self-supporting. However, he states that in later years where the mining had progressed to the dip, this ...

Practical way to quantify minerals from chemical assays at
Aug 01, 2013 Based on iron mineralogy (magnetite versus hematite) ore bodies are mined selectively and fed to two different lines. It is known that the ore bodies vary in their iron mineral chemistry and, at times, for the production of some special products (e.g. low/high vanadium or titanium), mining is done selectively from certain places.

Iron ore BHP
Iron makes up close to 5% of the Earth's crust. It takes around 1.6 tons of iron ore to produce one ton of steel. The chemical symbol for iron is 'Fe' because of its Latin name Ferrum. We use 20 times more iron (in the form of steel) than all other metals put together. Our iron ore trains are over 2.5km (264 ore cars) long, meaning it can take ...
