Modeling of the Mount Isa rougher-scavenger copper …
A flotation model developed at the Julius Kruttschnitt Mineral Research Centre was used to predict the performance of copper rougher and scavenger circuits at the copper concentrator at Mount Isa Mines. The model describes the kinetic response of an ore in a flotation cell in terms of ore floatability, cell characteristics and froth recovery. …

Basic Flotation Circuit Design
The tails when they enter the feed end of the scavenger cells become the SCAVENGER HEADS. Because the amount of mineral that is in the scavenger concentrate is' very small in relation to the waste that was gathered, it is often returned to the feed of the original bank of cells to be processed again.

Mechanism and Regulatory Function of CpG Signaling via Scavenger …
It is well established that CpG promotes pro-inflammatory cytokine and antibody production by B cells via the Toll-like receptor 9 (TLR9)-dependent pathway. However, scavenger receptors (SRs) are also capable of binding such pathogen-derived molecules, yet their contribution to CpG-induced signaling events has not yet been evaluated. Here we …
