• 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.
