Tacmin Madini is a growing and diversified group of expertise and associates who specialize in the provision of multi-disciplinary advice and solutions to the Openpit minerals sector
Is a diamond mine located in Mazvihwa, south central Zimbabwe. The mine is a combination of open pit and underground construction.
The mine produces about 250,000 carats per annum through its processing plant. A mining reserve comprising three kimberlite pipes containing 16.5 Mt grading at an average of only 0.9 carats per ton has been outlined. At a planned production of 500 000 tons per year, the mine could produce 450 000 carats per year.

Rössing:
Is now the third-largest open-pit uranium mine in the world. Mining consists of three main activities: drilling and blasting to break the rock; loading the ore by shovels unto trucks; and hauling it from the pit, either to the processing plant if the uranium grade is high enough for efficient processing, or stockpiling the waste in dumps adjacent to the pit.
The uranium in Rössing’s lease area is found in very hard and abrasive granitic rock called alaskite. To move the required amount of ore and waste, we have to conduct blasting operations in the open pit at least once a week. One blast loosens between 150,000 and 500,000 tons of rock, much of which does not contain sufficient uranium-bearing rock to justify processing it. About 3.5 tons of uranium-bearing rock is needed to produce 1 kg of uranium oxide.

Richards Bay Minerals:
Is one of the world's foremost producers of titanium minerals, high purity pig iron, rutile and zircon as well as space age metals.
RBM uses a dredge mining operation to extract and separate the heavy minerals - ilmenite, rutile and zircon (about 5% in volume) from the sand dunes.

Simandou: In 1996, the Minister of Mining, Geology and Environment of Guinea met with Rio Tinto in London. He noted that the area Simandou, in south-east, had the potential resources of iron ore for which there was no active exploration and encouraged Rio Tinto to send an exploration team Guinea.
Since 1997, Rio Tinto has prospected along its entire concession, 110 km mountain range, with the help of field geologists, sounding equipment transportable by helicopter and road explorations allowing specialized survey devices to access remote areas of the site.
