Overview

Flotation separates minerals on surface properties, so almost every recovery problem is a chemistry problem presenting as an operational one. This week builds the chemistry from the surface up: wettability and contact angle, the electrical double layer, how a collector attaches to a mineral and why it sometimes attaches to the wrong one. Reagent selection, water chemistry and pH control follow from that, and the troubleshooting session works real plant symptoms backwards to their chemical cause.

It runs 7 times over the published calendar, in 6 cities and live online. Every date is the same programme with the same content and the same certificate.

What you will be able to do

  • Explain flotation in terms of surface chemistry rather than recipe.
  • Select collectors, frothers, depressants and activators on mineralogy.
  • Diagnose the effect of pH, ionic strength and water quality.
  • Relate laboratory testwork to plant performance.
  • Trace a recovery or grade problem back to its chemical cause.

Who should attend

Metallurgists and process engineers, plant chemists and laboratory staff, flotation operators and supervisors, and reagent technical representatives.

Is the level right for you?

This is a foundation level programme. It assumes you are working in or moving into the area it covers, and it is built around your own material rather than a case study. If you are unsure, ask an advisor before registering rather than after.

Ask an advisor

How it is taught

Short input, then work. Across 5 days of roughly 6 teaching hours each, the balance sits deliberately with the second: a programme where the trainer talks for six hours produces notes rather than capability.

  • Your own material

    Exercises run on situations delegates bring, not on a case study written for a different organisation in a different decade.

  • A capped cohort

    Small enough that everybody is asked something. Executive programmes are capped tighter still.

  • Practice under scrutiny

    The difficult conversation, the challenged assumption, the decision defended out loud. Judgement is not built by watching.

  • Something to take back

    Each day ends with a thing you can use on Monday rather than a slide deck you will not reopen.

The programme, day by day

Day 1Surfaces

Surfaces

  • Hydrophobicity, contact angle and attachment
  • The electrical double layer and zeta potential
  • Mineral surfaces and their natural behaviour
Day 2Reagents

Reagents

  • Collectors and their selectivity
  • Frothers and froth structure
  • Depressants, activators and modifiers
  • Dosage, staging and addition points
Day 3Water and pH

Water and pH

  • pH control and its effect on selectivity
  • Dissolved ions and recycled water
  • Water quality variation and its consequences
Day 4From bench to plant

From bench to plant

  • Batch and locked cycle testwork
  • Scale up, and where it misleads
  • Sampling and assay reliability
Day 5Troubleshooting

Troubleshooting

  • Recovery loss by size fraction
  • Grade, and misreporting minerals
  • Froth problems and their chemical causes

What you leave with

  • A reagent suite rationale for one ore type.
  • A water chemistry review for your own circuit.
  • A troubleshooting sequence for recovery loss.

The certificate

A GATI certificate recording what you attended, issued after the programme has run and attendance has been taken. Attending at least 80 per cent of the days earns a certificate of completion; attending less earns a certificate of attendance stating exactly what was attended.

Every certificate carries a code that anybody can check against GATI's own record, which is what makes it worth holding. It records participation. This site will not imply one it does not have.

Questions

Who is Flotation Chemistry Fundamentals for?
Metallurgists and process engineers, plant chemists and laboratory staff, flotation operators and supervisors, and reagent technical representatives. It runs at foundation level within Mining Engineering, so it assumes you are working in or moving into that area rather than meeting it for the first time. If you are unsure whether the level fits, ask an advisor before registering rather than after.
How long is it, and what does a day look like?
5 days, running to roughly 6 teaching hours a day. Sessions are built around your own material rather than a case study, so a day alternates between short input and working on something you brought. The full outline is on this page, day by day.
What does it cost, and what is included?
The next published date is Live online at US$995 per delegate. The fee covers tuition, all programme materials and the certificate. Travel, accommodation and visas are arranged by the delegate. Fees vary by city, and every published date shows its own.
Can it be delivered for my organisation only?
Yes. Any published programme can run as a private cohort, on dates that suit you, in your city or online, built around your own material. That is a different conversation from registering an individual, and it starts with what capability you are trying to build rather than with a course title.
What certificate do I get?
A GATI certificate recording what you attended, issued after the programme has run and attendance has been taken. Attending at least 80 per cent of the days earns a certificate of completion; attending less earns a certificate of attendance stating exactly what was attended. Every certificate carries a code that anybody can check against GATI's own record.
Is the online version the same programme?
Yes. The same faculty, the same material, the same cohort cap and the same certificate. It is not a recording and it is not a reduced version. It exists because travel budgets and visa timelines rule people out of a room they should be in. The classroom version runs in Dubai, Cairo, Nairobi, Kampala.

Want to take this further?

Register on a published date, or tell an advisor what you need and they will come back with something specific rather than a brochure.
