  • Sees interest in heavy machines
  • Got a little bit into 3D printing
  • 2 months backlog from COVID, now lower risk. Catching up at work now.
  • After 4-5 months will review if can spend more than 20 hours/week
  • Wants a chapter.
  • Engineers, mechanical, structural, electrical. Has a permanent team of lead engineers.
  • Metallurgical, process engineer - Lesego
  • Junior engineers, not permanent.
  • Mining. Process plant - they don't do greenfield (from scratch). Goes into operations that exist, or expansion. Feasibility studies.
  • Spiral system for washing chrome. Did a small plant. Electrical motors. Cheaper to run on electrical.
  • 'I'm a metallurgist'.
  • Production and smelting facility, and creating the opportunity for others. Interested in steel.
  • 3 steps in PMG - 1. concentrate by crushing, expose mineral. 2. Flotation or spiral, float - cocentration. You add surfactants. Aerophilic. Depressors. Silicates and other oxides - makes them more hydrophilic so they sink. Xanphaste,
  • Xanphate - https://en.wikipedia.org/wiki/Xanthate#:~:text=Xanthate%20usually%20refers%20to%20a,most%20xanthate%20salts%20are%20yellow.
  • 600 rand pay in conulting work
  • Frother - petro-based materials
  • Easier to buy the concentrate - chromate, and then mix with iron source to get ferrochrome
  • South Africa is the window to Africa.
  • https://en.wikipedia.org/wiki/Mintek
  • Obviously I want it all. Agile and rapid development. Printer + Torch first. Then heavy machines.
  • Movement entreneurship - yes! Always looked for goals beyond reach.
  • Pressing world issue - priviliges at the cost of many people. Being forgotten... View is opposite.
  • So OSE can help on this issue.
  • Skill soft skill ok. But practical skills of building things is the missing link. More artisinal.
  • Artisinal people would make more money. Practical skills are a must.
