Moroccan reserves of phosphates are the largest ones in the world. They are estimated to more than 85 billion m3. The drainage of the phosphate rock from the mines site to the chemical sites, which is currently done by train, requires dry phosphate to lower the humidity in order to carry it cheaply.
However the chemical processing of raw phosphates, to get the final products (phosphoric...

Minera Los Pelambres (MLP) is located in the IV Region of Chile, with a mine located at 3100 masl and a concentrator located at 1600 masl. MLP started its operation in the year 2000 and by 2015 it was one of the 10 largest producers of copper concentrate in the world, achieving 405.300 tons of copper and 9.000 tons of molybdenum concentrates in 2013. MLP has established within its goals to...

The copper mining and ore processing is one of the most stable and profitable branch of the Polish economy and the fastest growing industry. However the technologies used lead to high losses of valuable and so called deficit metals (rare earths, uranium and copper) in solid wastes streams. The development and implementation of hydrometallurgical technologies is a solution feasible from the...

Fluid catalytic cracking (FCC) is one of the main processes used for processing the crude oil in refineries. The efficiency of the cracking process depends upon process parameters such as residence time, residence time distribution, radial distribution and axial mixing of catalyst and gas phases in various sub-units such as riser, disengager, stripper and regenerator of the FCCU. Radiotracer...

The global mining industry relies on elemental analysis throughout their value chain. The development of near real-time analysis techniques such as on-stream and hand-held X-ray fluorescence allows assay data to be used for process control and optimisation.
Unfortunately, current methods have insufficient sensitivity to measure metals such as gold, which are mined at concentrations of a...

Damage to the internal surfaces of piping systems of process industries is caused by continuous exposition to mechanical and chemical processes throughout their life span. This paper reports on a preliminary evaluation as to whether radiotracer techniques can be used in the detection of the two most frequent deterioration processes in an oil production and refining, viz. corrosion and scaling....
