Million in contracts and capital raising
The efficiency of a metallurgic process depends, to a large extent, of the adequate and timely operational decision making in light of the variability of the physical and chemical quality […]
Landslides and mass movements can endanger workers and could cause the total shutdown of the mine. Gesecology developed a technology that integrates and correlates geotechnical and geological data, using mathematical […]
Manual technical conciliation for slope design and construction is time consuming and its results may be inaccurate. Geoblast developed and implemented a software, which compares and consolidates geotechnical data and […]
HighService Technology developed a mill lining and wear plates abrasion sensor (the SSD technology) which allows online detection of the components
Labour productivity in the mining industry dropped 20% in comparison with 2000, in Chile and internationally, as stated by the Chilean Copper Commission (Cochilco) in 2014. This is an important […]
The Trommel is a classification system per size of ore coming from the mills. It downstream allows passing of the ore complying with required grading and returns the one requiring […]
Breakdown voltages and energy leaks are common in EW tankhouses in copper operations. Its monitoring is manual, costly and slow. TESRA adapted existing technology to develop an automatic thermal control […]
As mining projects increase their operation time and growth, they are subject to changes in their form and structure, which, despite having been considered in their designs and construction, need to be monitored and modeled with precision to avoid catastrophic situations.
The climatic conditions and high altitude present in Chilean mining, damage heavy-duty haul truck engines, eroding their components and reducing their lifecycle.
The OTR tire (Off-the-Road tire), is a highly necessary supply for the operation of any load vehicle and plays an enabling role in ore transportation within the extraction process. The […]
The availability of mining power shovels is an important factor for extraction and loading processes.
Water plays a significant role in copper production. It mainly participates in the concentration, hydrometallurgical, foundry and refinery processes.
For mining companies to increase the metallurgical efficiency of the leachingheaps, it is necessary to monitor and manage these operational variables in a timely manner to maximize copper extraction.
Bioseal is a bio-technological product created to reduce and control emissions of particulate matters such as roads and ramps, tailing dams, slopes, hillsides and landfills, among other.
