NBChem has had the privilege of working with Rasp for many years on frother and collector chemistries in the ongoing support of site production targets and changing ore types. NBChem supplies a non-DG frother with similar performance to MIBC, albeit ~10% more efficient. While MIBC is always a brilliant starting point for selective applications, the go-to frother cannot be used at RASP due to proximity to Broken Hill township due to its Dangerous Goods classification.

This testwork program undertaken at Rasp is one of numerous active projects that NBChem is actively engaged in to replace conventional xanthate collectors with other specialty collector products. Although xanthates are very effective and powerful flotation collectors, there are many issues associated with the storage, handling and transport of these spontaneously combustible solids.
