“…The difference in the Zr-content of the S-and E-series can be attributed to the higher density and hardness of the employed suldic reaction mixtures compared to its elemental reaction mixtures. 33 The ICP-OES results were further supported in trend and magnitude by particle induced X-ray emission (PIXE) measurements serving as an independent method for the Zr-quantication ( Fig. S9 †).…”

“…balls) is the prominent item that raises the milling operation costs (Vermeulen, Howat, & Gough, 1983). As an example, the annual global consumption of steel alone exceeds 600000 tonnes (Massola, Chaves, & Albertin, 2016). Therefore, reduction of the wear is necessary to reduce the total operating costs and increase profitability (Tolfree, 2004).…”

“…In 2007, US Department of Energy reported that, comminution consumed about 50% of the total mining energy in the United States (U.S. DOE, 2007), as depicted in Figure 1. Also, it has been reported that approximately 50% of comminution operation costs are due energy consumption, while the other half is attributed to liner/charge wear (Radziszewski, 2002;Massola, Chaves, & Albertin, 2016). On other meaning, the total costs of comminution are equally divided between energy consumption and replacement of worn grinding media.…”

This study aims to estimate the wear of the middle chrome grinding balls in both dry and wet grinding media. The selected ball mill for this study is located at Mahd Ad Dahab Gold Mine, Saudi Arabia.Methods. The amount of wear is determined based on the decrease in the balls weight with respect to grinding time. Findings.The results show that, the loss in the balls weight is proportionally related to their diameters. Also, the amount of wear is reduced by almost 12% when using wet grinding than dry medium.Originality. This study provides a methodology to evaluate the performance efficiency of grinding operation as a function of the amount of wear results in the grinding medium. Practical implications.Grinding is an intrinsic step in almost all mineral processing. Such step is very expensive; but, it is essentially required to reduce the size of the run-of-mine (ROM) material, to liberate valuable minerals from the ore matrix and to increase the surface area for higher reactivity. Thus, this study sheds light on the cost of wear rate associated with ball mill at Mahd Ad Dahab Gold Mine, Saudi Arabia, and its significant impact on the efficiency of grinding operation.

“…However, the corrosion mechanism's contribution to overall wear is still unreported. The wear mechanism is a critical factor for increasing the efficiency of the grinding ball [15]. It has been shown that the presence of appropriate neutralizer materials such as Mn, Cr, Be, Co and Sr can change the structure of the process to less dangerous forms [16][17][18].…”

Our object of research is to combine the properties of Mn and the advantages of Fe-Al-C to improve the performance of grinding ball materials. Three Fe-5Al-1C alloys with compositions of 15 wt% Mn (FAM15), 20 wt% Mn (FAM20), and 25 wt% Mn (FAM25) were investigated. Argon gas was used to assist the removal of dissolved oxygen and to control the formation of metal oxides during Fe-Al-Mn-C (FAMC) fabrication. Microstructure analysis was conducted using scanning electron microscopy, and the Vickers microhardness tester was used to evaluate hardness. To guarantee the Fe-5Al-1C-Mn alloy phase, X-ray diffraction (XRD) test was performed. The EDS test was carried out to show the composition at different points and to observe the presence of several phases in the FAMC alloy system. A pin-on-disc method was employed for a dry sliding wear test, and corrosion testing was performed using the three-electrode cell polarization method. With the addition of Mn, the Vickers hardness of the FAMC alloy raised from 194.4 VHN at 15 wt% to 265 VHN at 25 wt%. The tensile strength and fracture elongation values were 424.69 MPa, 27.16 % EI; 434.72 MPa, 33.6 % EI; and 485.71 MPa, 38.48 % EI for FAM15, FAM20, and FAM25, respectively. A crucial factor for increasing the performance of grinding ball is the wear mechanism. The wear rate results for FAM25 show a decline of more than 57 % compared to FAM15 due to an increase in the hard intermetallic area. The addition of Mn elements increased the corrosion resistance of the FAMC alloys; the lowest corrosion rate occurred at 25 wt% Mn content at up to 0.036 mm/yr. According to the experimental results, the FAM25 alloys have the highest mechanical and corrosion resistance of the three types of alloys. The FAMC alloy is a promising candidate for application as a material for grinding balls by optimizing the Mn content
