MINERAL PROCESSING METHOD OF THE WEEK - GRAVITY SEPARATION!!

Gravity methods use the difference in the density of minerals as the concentrating agent. In heavy-media separation (also called sink-and-float separation), the medium used is a suspension in water of a finely ground heavy mineral (such as magnetite or arsenopyrite) or technical product (such as ferrosilicon). Such a suspension can simulate a fluid with a higher density than water. When ground ores are fed into the suspension, the gangue particles, having a lower density, tend to float and are removed as tailings, whereas the particles of valuable minerals, having higher density, sink and are also removed. The magnetite or ferrosilicon can be removed from the tailings by magnetic separation

MINING METHOD MONDAY - SHRINKAGE STOPING!!

The shrinkage stoping method is similar to cut and fill, but instead of removing the ore after blasting and backfilling, the initial broken ore is left in the void to create a working platform for the next level (and to support the wall stability of the stope). After all the planned levels have been blasted, then all of the ore is removed for processing. This method is very selective and keeps dilution low, but requires many active stopes because ore is not removed from each mining area until completion – meaning longer lead times for ore to get to the process plant compared to cut and fill operations - New Pacific Metals Corp.

HAULSIM PRODUCTIVITY SIMULATIONS!!

Are you 100% confident that your Excel calculations are correct in determining fleet numbers? Are your roads accurately set-up in terms of stop signs, single carriage areas, steep gradients, single-bay dumps? What happens when you have congestion in your pit, how does Excel cater for that? With the HAULSIM simulations you can set up your site accurately to generate realistic results in terms of fleet numbers. The simulations allow you to run a host of possible scenarios, to ensure you understand the flex of your loading & hauling system, and better prepare for possible surprises. Doing a little homework now might just save you years of agony when things don’t pan as out as hoped, and more im

MINE PLANNING BASICS FRIDAY - HAUL ROAD EFFECT ON PIT LIMITS!!

A very basic illustration from Venkat Masabattula of the effect of introducing a haul road into the mine design. Note the effect on the average pit slope angle in the illustration bottom left. That's why I would recommend doing mine design iterations as well when selecting truck sizes for your fleet. Bigger trucks mean wider roads means more waste for same ore... comments welcome!

MINE SCHEDULING!!

Know the feeling... when you're losing precious time because of fighting the software instead of running iterations and scenarios... You will never have confidence in your schedule if you do not have 2 or 3 scenarios to test the flex of your system. Your superiors want a number of options, not just one answer. RPMGlobal's XPAC SOLUTIONS products (OPMS & SMS) 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!

MINING ROCKSTAR OF THE WEEK – LIMONITE!!

Before modern mineral analysis, the name "limonite" was given to many of the yellowish to yellowish brown iron oxides produced during the weathering of iron-bearing rocks or deposited as bog, lake, and shallow marine sediments. Researchers who studied "limonite" discovered that it is amorphous and has a variable composition. It often contains significant amounts of iron oxide minerals such as goethite and hematite. This research revealed that the material called "limonite" does not meet the definition of a mineral. Instead, limonite is a mineraloid composed mainly of hydrous iron oxides that are often found in intimate associations with iron minerals. Today the word "limonite" is used as a f

MINE DESIGN!!

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

SHOWCASE IRON ORE MINE OF THE WEEK – CHICHESTER HUB!!

Located in the heart of the Pilbara, the Chichester Hub is made up of Fortescue's flagship minesite Cloudbreak and the second minesite Christmas Creek. The total Chichester Hub produces 90 million tonnes per annum (mtpa) of iron ore plus an additional five mtpa from a joint venture with BC Iron. Fortescue Metals Group Ltd (Often referred to as FMG) is an Australian iron ore company. Fortescue is the fourth largest iron ore producer in the world after BHP Billiton, Rio Tinto, and Vale. The company has holdings of more than 87,000 km2 in the Pilbara region of Western Australia, making it the largest tenement holder in the state, larger than both BHP Billiton and Rio Tinto - "Mining.com", Wikip

IS YOUR PIT OPTIMISATION ADJUSTED FOR THE CURRENT ECONOMY??

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...

MINERAL PROCESSING METHOD OF THE WEEK - FILTRATION!!

Filtration is the separation of a suspension into a solid filter cake and a liquid filtrate by passing it through a permeable filtering material. Important factors in this process are the properties of the suspension (e.g., size distribution, concentration), the properties of the filtering materials (e.g., the width and shape of pores), and the forces applied to the suspension. Filtration is carried out in gravity filters (screens, dewatering bins), in centrifugal filters (screen centrifuges), in vacuum filters (drum cell filters, disk filters), or in pressure filters (filter presses). Such devices make it possible to produce filter cakes containing 8 to 15 percent moisture - Encyclopedia Br

MINING METHOD OF THE WEEK - CUT AND FILL MINING!!

In this selective mining method, the void created by mining is backfilled with a mixture of waste rock or tailings (with cement sometimes added to strengthen the mixture), which helps support the walls of the empty space. This type of mining is typically done upwards from lower levels, so the fill is also used to provide a new working level for further mining. Cut and fill mining can be expensive, but this method allows for highly selective mining with less waste rock or low-grade ores mined-out (which keeps production costs low). It’s typically used in situations where the ore body dips steeply or is very irregular, which makes mechanized long-hole methods difficult to implement - New Pacif

MINING ROCKSTAR OF THE WEEK – LEPIDOLITE!!

Lepidolite is the name of a rare lithium-rich mica mineral that is usually pink, red, or purple in color. It is the most common lithium-bearing mineral and serves as a minor ore of lithium metal, with rubidium and cesium sometimes being byproducts. When impregnated with quartz, lepidolite is used as a minor gemstone. Flakes of lepidolite are sometimes responsible for the color of pink and red aventurine - "Geology.com".

SHOWCASE IRON ORE MINE OF THE WEEK – YANDI!!

The Yandi mine is an iron ore mine located in the Pilbara region of Western Australia, 90 kilometres north-west of Newman. It should not be confused with Rio Tinto's nearby Yandicoogina mine, which is also sometimes shortened to Yandi. 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. BHP Billiton is the second-largest iron ore mining company in the Pilbara, behind Rio Tinto and ahead of the Fortescue Metals Group. As of 2010, BHP employs 8,000 people in it

MINING METHOD MONDAY - LONGWALL STOPING (METALLIFEROUS)!!

After starting an overhand stope, the shape in which the back is carried is often of prime importance. Position A in the figure illustrates the method of carrying a flat or longitudinal back (the term long-wall is used sometimes when the vein lies nearly flat). In this method the benches or breasts are frequently made of a height sufficient to allow of a square set being placed. This is done at Butte and it is often referred to as breast stoping - 911 Metallurgist.
