Innovation, optimization, sustainability;
the edge of our intellectual property portfolio.
Ultra low and ultra high temperature reference electrodes for corrosion measurement or any place where control is necessary.
Clean, sustainable and efficient extraction of metals. New technology for copper leaching and refractory ores.
Novel process for fly ash based building materials, very high compressive strength as well as water resistant products.
In our group we have several important technologies that lead to improved metal recovery rates. One of our methods utilizes a high concentration of sulfuric acid and maintains the sulfuric acid at this high concentration level in a glass-lined reactor for obtaining high copper extraction with short residence times. This is an improvement by way of the ARV Process for metal extraction with increased recovery rates. Other alternative technologies focus on value generation from copper containing effluents (HydroS) that can be used to replace the SART process (NaSH) as a key example. In addition to this the MetOxs process can be a key solution for the leaching of refractory ores as well as traditional leaching using a clean, efficient and sustainable approach.
New technology for waste, water evaporation management. Novel design can be used at open sea for plastic recovery and floatovoltaics.
Value extraction for building materials as well as heat recovery from mining processes (i.e. smelting slag).
New technology for tailing mineral extraction. This includes value proposition of mineral recovery where conventional methods fail or are too costly.
The mining industry, metal plating industry, the manufacture of fabric and other industries generate effluents with heavy metals or solutions rich in metals that cause water pollution and which can be recovered or removed by chemical precipitation by our innovative chemical processes.
Metoxs has developed a highly groundbreaking, efficient and fast process to produce H2S (g) where sodium hydroxide (NaOH), elemental sulfur (S) and water (H2O). This process has the characteristic of a lower cost of production that the existing processes and this will depend exclusively on the cost of the reactants.
Hydrogen sulphide (H2S) can be easily used for the precipitation of metals that are in solution. For this purpose the use of H2S generally leads to better metal removal efficiency and generates a more compact, stable and reusable product unlike the respective hydroxides and carbons that are generated with traditional methods..
In the mining industry, slags are glassy materials that are left over when metals are extracted from ores, have been a problem since the beginning of the industrial regime. Generally, these are considered waste. An example of such material is copper slag which is produced during matte smelting and converting steps of pyrometallurgical production of copper. During the smelting process there are two liquid phases involved, one is a copper-rich material and the other slag. A rough estimate is that for every ton of copper production, around 2.2 tons of slag is generated annually. Each year around 25 million tons of copper slag worldwide are generated as a result of copper mining. The MetOxs® Process is a key component to be able to extract value from these mine tailings. Part of our technology also encompasses the recovery of waste heat from smelter slag for use in the mining facility.
