The worldwide issue of water shortage and the experience of our technical team have driven us to offer all types of flocculants (anionic, cationic, nonionic and rheological). We have high, intermediate and low molecular weight flocculants with different ionic charges to improve the speed of tailing and concentrate sedimentation. This allows for the optimization of the recovery of processed water. In addition, we have the capability of improving the quality of processed water with products such as: dispersants, antiscalants and corrosion inhibitors, which must be analyzed on a case-by-case basis. Products:
  • FLOCCULANTS
  • ANTISCALANTS
  • COAGULANTS
The addition of our leaching agents allow for the extraction of gold and silver from rocks. Products:
  • SODIUM CYANIDE
  • ACTIVATED CARBON
  • ZINC POWDER
  • SODIUM METABISULFITE
We carry the Orfom SX 80 Diluent by Chevron Phillips, a high-quality product with excellent performance during the SX stage, which is compatible with all extractants on the market.  The Orfom® SX solvent extraction diluents are manufactured to stringent specifications to guarantee the product’s consistency and optimize the separation of the phase during the recovery of metals, including, among others, copper, cobalt, nickel, platinum, palladium, uranium, vanadium, beryllium, zinc group elements and lanthanides. Products:
  • EXTRACTANT DILUTER 
  • COBALT SULFATE

JHMT China begun operations in 2012 to manufacture forged ball mill balls in diameters ranging from 1” to 5”. Certified under ISO 9001, ISO 14001, OHSAS 18001. This is a fully automated plant that uses a unique heating system that allows for a uniform microstructure hardness, offering a high impact and low breakage rate.
