The role of surface roughness in the wettability and floatability of quartz particles

, 2020
Surface roughness affects both the adsorption capacity of collector and mineral flotation separation. To investigate the role of surface roughness in quartz flotation, in this study, quartz particles were ground by different mills to produce two quartz ...

Flotation separation of smithsonite from quartz using calcium lignosulphonate as a depressant and sodium oleate as a collector

Minerals Engineering, 2019
Flotation separation of smithsonite from quartz is difficult due to the dissolved zinc species activated the quartz flotation. To solve this problem, calcium lignosulphonate (CLS) was introduced as a depressant for quartz in smithsonite flotation when ...

Reverse flotation separation of quartz from phosphorite ore at low temperatures by using an emerging Gemini surfactant as the collector

, 2020
Quartz, the gangue of phosphorite ore, is challenging to be separated at low temperatures. In this work, an amine-typed Gemini surfactant, N,N'-bis(dodecyldimethyl)-1,4-butane dibromide (BBD) was recommended as an emerging collector for reverse flotation
