ONLINE FLOTATION TESTS MASS BALANCING
Rougher fotation tests:
Flotation testsmass balance calculations for a rougher flotation circuit with known individual concentrates and tailing assays, a scavenger flotation circuit with known individual concentrates and tailing assays,
a cleaner flotation circuit with known individual concentrates and tailing assays, a preflotation circuit with known individual concentrates and tailing assays. (opens in a new tab/window)
Rougher-Cleaner fotation tests:
Flotation tests mass balance calculations for a rougher circuit with known tailing weight and assays whose concentrate stream feeds a cleaner circuit (rougher-cleaner), a cleaner circuit followed by a recleaner circuit, or
a preflotation followed by preflotation cleaner circuits (opens in a new tab/window)
2 x Rougher-Cleaner fotation tests:
Two rougher-cleaner circuits (e.g., sequential lead rougher-cleaner followed by zinc rougher-cleaner flotation circuits).
(opens in a new tab/window)
Rougher-Cleaner & Rougher fotation tests:
Rougher circuit with recalculated feed, concentrate and tailing; whose concentrate and tailing streams feed a cleaner and second rougher circuits, respectively.
(opens in a new tab/window)
Rougher-Scavenger fotation tests:
Flotation tests mass balance calculations for a:
- Rougher circuit with known individual concentrates assays whose tailing stream feeds a scavenger circuit (rougher-scavenger).
- Sequential rougher flotation of a polymetallic ore (e.g., a lead rougher followed by a zinc rougher circuits).
- Preflotation followed by rougher circuits (e.g., carbon preflotation followed by copper rougher circuits).

Three rougher banks fotation tests:
Flotation tests mass balance calculations for a:
- Sequential rougher flotation of a polymetallic ore (e.g., copper, lead and zinc rougher circuits).
- Rougher-scavenger followed by another rougher circuit (e.g., lead rougher scavenger plus zinc rougher).
- Preflotation followed by rougher-scavenger or two rougher circuits.
