Flash Flotation Cell - 911 Metallurgist

2016-6-1  NO SUPERVISION is required for the operation of a Flash Flotation Cell because it treats the ball mill discharge automatically and the operator need be concerned only with the normal operating control of the grinding circuit. No special reagents are required; the total reagent consumption is equal or less in plants where Flash Cells are now operating.

Recovery of Copper from the Slag of Khatoonabad

2013-6-5  The purpose of this study was the recovery of copper from the slag of Khatoonabad Flash Smelting Furnace (FSF) (Kerman Province, Iran) using the flotation method. Flash smelting is an oxidizing process containing high grade copper matte. The copper content of FSF slag is relatively high, and must be recovered before disposing of the slag.

Kiln vs flash calciner - FLSmidth

The kiln system provides the gradual heating and extended retention time (normally ~30 minutes) needed to effect the conversion on large particles. Conversely, a gas suspension calciner (GSC) is best suited for spodumene concentrate that has a PSD less than 1mm, which is common for concentrates produced via the floatation process.
