Hematite is one of the most abundant minerals on Earth's surface and in the shallow crust. It is an iron oxide with a chemical composition of Fe2O3. It is a common rock-forming mineral found in sedimentary, metamorphic, and igneous rocks at locations throughout the world. Hematite is the most important ore of iron. Although it was once mined at thousands of locations around the world, today almost all of the production comes from a few dozen large deposits where significant equipment investments allow companies to efficiently mine and process the ore. Most ore is now produced in China, Australia, Brazil, India, Russia, Ukraine, South Africa, Canada, Venezuela, and the United States. Hematite

Battling with the software to set up a mining schedule? We all know the feeling... when you're losing precious time because of fighting the software instead of running iterations and scenarios...

RPMGlobal's XPAC SOLUTIONS products allows you to do just that - run scenarios instead of suffering in silence. With almost a decade of open pit scheduling experience allow me to help you create options for your company, so you can make informed decisions, and understand the risks with confidence!

The Area C mine is an iron ore mine located in the Pilbara region of Western Australia, 92 kilometres west-north-west of Newman. The mine is majority-owned (85 percent) and operated by BHP Billiton, and is one of seven iron ore mines the company operates in the Pilbara. The company also operates two port facilities at Port Hedland, Nelson Point and Finucane Island, and over 1,000 kilometres of rail in the Pilbara. The Area C mine is part of the Mount Goldsworthy joint venture, together with the Yarrie and Nimingarra mine, with the latter two being in care and maintenance since 2014 and 2007 respectively. BHP Billiton is the second-largest iron ore mining company in the Pilbara, behind Rio Ti

How sure are you that your mine designs have the minimum number of switchbacks? Have you tested the impact of having one switchback less, how that reduces your strip ratio and down-the-line costs, not to mention the health & safety of your employees ...? What about your benches & stacks, do they honour the geotechnical slope angles to prevent slope failure...? Your ramp systems on your interim high-walls - do they tie up with your final design and serve as dual access for that rainy day when you need it most...? Difficult questions I know, but prevention is better than cure as they say. Using state-of-the-art mine design software and almost a decade of design experience, I can help you sleep

This is a YouTube training film of ACC on safe handling of explosives during mining, posted by K Jayadev.

The mining industry is notorious for its volatile nature as commodity prices fluctuate. History shows that it's the companies that can adjust to the market changes the quickest that lead the pack. Mining on a 5-year old mine design that was based on a Whittle shell all those years ago can mean you're either leaving value in the ground, or more detrimental, you're now mining in areas where profitability is going South... With almost a decade of Whittle open pit optimisation experience I can help you dust off that old Whittle model, and make sure your mine is set up to run at maximum profitability under current economic conditions... Doesn't hurt to make sure now does it...

The figure below shows various methods of working the back in overhand stoping. To start the stope, if the ore is low grade and timber is scarce, a pillar or pillars are left above the level as shown in A, and if the ore is high grade it is all removed above the level and stulls are placed as shown at B. To start a stope as shown at B, a cutting out or lead stope is broken immediately above the level as shown at D. C is a wide raise or raise stope, which is one method of opening an overhand stope, and E is a drift stope, which is a term used in the Lake Superior copper mines and means a wide and high drift as a start for the overhand stoping - 911 Metallurgist.

This illustration from Caterpillar shows typical haul road design considerations for a dual-carriage road. What's your mines standard for haul road width in terms of dual-carriage roads?

So, you had a consultant do mine planning work on your project - great. The consultant used a variety of specialised software packages to do e.g. a Pit Optimisation, Mine Designs and a Mining Schedule - great. The consultant gave you Excel spreadsheets, a PowerPoint presentation with screenshots and a Word document of the work - great. The consultant also showed you on his/her computer what the work looks like in the software - great. But eventually the friendly consultant leaves and you don't have the software to open the work and look again. What if the screenshots don't reveal the ramp you need to see? Or you need to show your colleague all the great work quickly and efficiently, without

Halite is the mineral name for the substance that everyone knows as "salt." Its chemical name is sodium chloride, and a rock composed primarily of halite is known as "rock salt." Halite is mainly a sedimentary mineral that usually forms in arid climates where ocean water evaporates. However, many inland lakes such as the Great Salt Lake of North America and the Dead Sea between Jordan and Israel are also locations where halite is forming today. Over geologic time, several enormous salt deposits have been formed when repeated episodes of seawater evaporation occurred in restricted basins. Some of these deposits are thousands of feet thick. When buried deeply they can erupt to form salt domes

This method is really a combination of several different methods of stoping. The figure is an illustration of the method, and shows half of the vein cut away where the stoping is being done. The miners go from the haulage level up the raise into the sublevels. On the first sublevel they will blast into the shape of funnels the raises that come up from the haulage level, and after working back, the slice, s, by breast stoping will drill holes at a and shoot part of this bench down into the raises. On the second sublevel the miners work back the slice, s, and then with down holes at b will blast the remainder of the first bench down into the raises, and with uppers at c shoot off part of the s
