A Study on the Utilization of Ultrasonic Pretreatment in Zinc Flotation

Abstract: This paper deals with the investigation of the effect of ultrasonic pretreatment on the mechanical flotation of zinc from lead-zinc-copper ore. After the chosen flotation parameters such as KAX dosage, frother amount, flotation time, stirring rate and amount of Na 2 SiO 3 , were optimized by flotation experiments without ultrasonic pretreatment, flotation experiments with ultrasonic pretreatment were carried out under these optimized conditions. The results obtained by both methods were compared. A zinc concen… Show more

“…According to the knowledge of the authors no efforts were done to compare the effect of UP by using a laboratory ultrasound bath on the zinc flotation recovery from the same ore using MF and CF except for our works [1,2]. Therefore, the aim of this work is to review and compare the effect of UP on the MF [1] and CF [2] performances in terms of Zn grade and recovery using the same ore. By this review study let's look for the answer to some questions like which one is more effective in terms of separation recovery and zinc grade? Secondly, is ultrasound really affecting on these two different beneficiation techniques positively?…”

“…The flotation conditions optimized for both flotation experiments were as follows: For MF tests [1], effects of Potassium Amyl Xanthate (KAX) describe it fully dosage, CuSO 4 dosage, 2-ethyl hexanol dosage, residence time, stirring speed, and Na 2 SiO 3 dosage on MF performance were tested to hold the optimum conditions. For the effects of UP on MF tests, KAX dosage, CuSO 4 dosage, Aerofloat 211 dosage, Na 2 SiO 3 dosage, 2-ethyl hexanol dosage, optimum flotation time and stirring speed on the MF performance were set as 90 g/t, 400 g/t, 100 g/t, 50 g/t, 15 g/t, 4 min., and 1000 rpm, respectively.…”

“…Ultrasonic application refers to sound waves that vibrate at a higher frequency than 20 kHz (Farmer et al, 2000;Chen et al, 2020). The prevalently used frequency range of ultrasonic application energy is about 20-100 kHz (Donskoi et al, 2012;Kursun, 2014;Ghadyani et al, 2018). It is proven that ultrasonic application shows considerable effects on the mineral surfaces such as cleaning, degradation, reduction, oxidation, activation, etc.…”

“…These cavitations take place primarily on the phase boundary since solid/liquid interactions are weaker than liquid cohesion forces [34][35][36][37][38][39]. When high temperature and pressure are attained inside the cavitation bubbles, their diameter exceeds a critical value, they collapse asymmetrically in the vicinity of solids present within the liquid [34][35][36][37][38][39][40][41]. Asymmetric collapse leads to the formation of high speed micro-jets that have the potential to remove the gangue constituents adhered on the surface of iron mineral particles [40,41].…”
