Anglo American ordered a SpectraFlow Analyzer for optimizing the raw material sorting in their Los Bronces copper mine in Chile. This is the second order of the globally-acting Anglo American group and the first installation in the Republic of Chile. With the orders from the iron ore, gold, platinum and bauxite industries, this order expands the SpectraFlow application field to copper.


About Anglo American:

In 1917 Ernest Oppenheimer founded the Anglo American Corporation in Johannesburg, South Africa to start with gold mining. In 1945 Anglo American moved into the coal industry by acquiring Coal Estates. In the late 1940s and 1950s, Anglo American focused on the development further goldfields and became the world’s largest gold-mining group.


In 1961, Anglo American became a major investor in the Hudson Bay Mining and Smelting Company in Canada. In 1967, the company moved into the steel industry. From 1967 to 1975, it continued to grow and established a number of ventures, including the Mondi Group (timber, pulp and paper), Amgold (later AngloGold Ashanti) and then Amcoal (through the consolidation of several of its mining operations in South Africa and later known as Anglo Coal.  In 1999 Anglo American Corporation merged with Minorco to form Anglo American plc. Its gold mining operations were spun off into the separate AngloGold corporation, which in 2004 merged with the Ashanti Goldfields Corporation to form AngloGold Ashanti. From 2007 Anglo American acquired control of the Michiquillay copper project in northern Peru and the MMX Minas-Rio and Amapa iron ore projects in Brazil and later acquired stakes in the Pebble copper project in Alaska. From 2010 to 2017 the company underwent major restructuring and today it has sharpened its focus on the main commodities: Iron Ore, Coal, Base Metals (Copper, Nickel, Niobium, Phosphates), Platinum and Diamonds. Today Anglo-Americans employs 69.000 people with a revenue of about EUR 25 billion.


SpectraFlow Installation for Mine Optimization:



The SpectraFlow Crossbelt Analyzer is the online analyzer to be able to measure raw materials in on belt conveyors. As raw materials from the mine are processed through a crusher the raw material on the conveyor belt is statistically homogeneous and therefore the analytical results of the SpectraFlow Crossbelt Analyzer are very accurate. Based on these accurate results the operators can optimize the feeders into the crusher. This results in precise control of the raw material feed into the plant.


By using SpectraFlow an optimization of the raw material handling will be achieved.


Summarized benefits are:

  • No need of sampling. Sampling from conveyor belts is unrepresentative and slow for process optimization. Additionally sampling is very work intensive regarding operation and maintenance.
  • The analyzer together with the Control software is fully automating the stacking of the different qualities of the raw material. The analyzer delivers the analytical results and according the production requirements the software is adjusting the switching of the raw material feed.
  • Raw Material sorting can be done in real time and only the raw material with the required quality will be further processed.

This SpectraFlow order is the 13th order for the minerals industry and the 2nd order in South America. This order raises the installed based in Chile to 1 analyzer (1 Crossbelt) and worldwide to 49 analyzers (25 Crossbelt & 24 Airslide).


SpectraFlow Analytics Ltd. Switzerland are the experts in providing online analysis for the cement and minerals industry without any radioactive sources nor neutron generators. The NIR technology used for the SpectraFlow Analyzers is not requiring any permits or licenses and there are no restrictions in buying, importing or maintaining the analyzers. This results in very low operating costs and high availability of the analyzers combined with highly accurate measurement results.
