A Delta Premium can do everything if you have the right calibrations loaded onto it. Attached is a Delta Product Descriptions that will act like a menu of sorts. Scrolling down will show you what calibrations
Why are Chile and the world going back to underground mining?
The world of mining is going back to where it all begun: underground. According to the experts, the need to preserve the environment and the birth of new technologies are causing big companies to move back to underground mining. The trend is quite notorious in Chile, but is quickly spreading to other countries. Juan Carlos Guajardo, head of the Centre
Philippines launches project against the dangerous use of mercury in small-scalle mining
The United Nations Industrial Development Organization (Unido) teamed up with the Philippine government to fight for the elimination of mercury use in artisanal and small-scale mining in the country. The project is entitled “Improve the Health and Environment of Artisanal and Small-scale Gold Mining [ASGM] Communities in the Philippines by Reducing Mercury Emission”. The main goal is to establish a formal
Niton XRF Calibration Factors
On the Niton XRF, calibration factors are used to adjust for consistently high or consistently low readings from the XRF analyzer. They are calculated by graphing the data points created by plotting the percentage of each element as indicated by standard samples, against the percentage of each element as reported by the XRF analyzer. Then the linear regression function is
Activox Process for Refractory Gold
It was a proprietary and licensed process. Is essentially low temperature/low pressure oxidation. I think patent may have expired, which is why I refer to it as low temp/low pressure rather than Activox. It was developed for Nickel extraction but can also be applied to refractory gold extraction.

The consequences of the Marikana massacre one year later
Four days ago, the world pointed the first anniversary of the police massacre that killed 34 platinum miners in the northern town of Marikana, South Africa. The disaster happened last year, on August 16, and also wounded over 75 people. “The attack reminded many people of the massacres inflicted by white supremacist forces during the apartheid era, except this time it was
Australian software reduces coal-stockpiling hazards and increases safety
How can the mining companies effectively diminish some safety risks? Well, the firm Immersive Technologies has an idea: the SimControl 4.6, the latest version of the software used to control advanced equipment simulators released last May. The company that supplies surface and underground equipment simulator to the global mining industry updated its software to specifically address the issue of safety in
Nautilus Minerals’ flagship Solwara 1 might be closer to dive its toes in Papua New Guinea’s sea
Nautilus Minerals has gone through some bad times over the last year. The difficulties that are affecting the firm are mainly related to a commercial dispute that started in June of 2012 and involves the company and the government of Papua New Guinea. The most affected project was Nautilus’ flagship Solwara 1, linked to a deep sea mining project in the country’s
AngloGold Ashanti presents its new mining technology: it mines “all gold, only gold, all the time”
AngloGold Ashanti announced a new “game-changing technology” that can safely mine “all of the gold, only the gold, all the time”, said the firm’s new CEO Srinivasan Venkatakrishnan. There’s no drill and blast. Effectively it removes the seismic impact, brings a safe working environment, eliminates dilution and brings all of the gold out. AngloGold Ashanti recently announced it’s cutting 2,000 non-mining jobs. The decision

Changes in New South Wales mining assessments can boost corruption
The Government of New South Wales, in Australia, is preparing changes for minings assessments that could attract the increase of corruption, says the NSW Greens group. The changes recently announced are more focused on the economic benefits and that is raising general concern in the country. John Kaye, NSW Greens MP, claims these alterations will re-create a Labor’s coal-development at all costs type of mentality:

Innovative technology makes its debut in Khanyisa power project
The Khanyisa power project, under development in South Africa, will be the first project of its kind in the region to use the innovative circulating fluidised-bed (CFB) technology. The news was revealed at a workshop promoted by the Fossil Fuel Foundation, attended by the project manager Julian Eslait, who works for the company Anglo American Thermal Coal (AATC). Indeed, although CFB technology has already been internationally proven,
Roping HydroCyclone -Bad Operation
HydroCyclone Roping – Incorrect Cyclone Operation is often caused by too high a volume feeding into the cyclone. If the apex capacity is exceeded a condition known as roping may occur. Normally, the underflow sprays out of the apex. When roping occurs, the air core inside the apex collapses and the spiraling motion is almost lost. The discharge looks like a
Hydrocyclone Efficiency Curves
The Hydrocyclone Efficiency Curves are affected by many operating factors such as feed density, apex and vortex sizes and feed pump pressure. These factors will cause your cyclone classification to operate correctly, in roping or spraying mode. Everyone knows or has seen an “Ideal Cyclone Efficiency Curve” VS an actual real life hydrocyclone Efficiency Curves? I attach one here below (thanks
