“…In terms of energy saving, all the six chemical additives used in the study reduced the comminution energy significantly. However, the organic and inorganic modified amines, hydroxylamine, and the mixture of polycarboxylate and amines had adverse effects on the 28-day cement strength [80]. An economic analysis of the whole system showed that cement production using any of the chemical additives used in the study was more profitable than cement production without the chemical additive (Table 7).…”

“…Generally, there are two types of chemicals used, mostly for cement production. The first type is used to modify the surface structure of the particle to improve grinding, while the second type is used as a cement strength enhancer [80]. Any chemical material that can cause an improvement in ore size reduction when mixed with the feed is termed a chemical additive.…”

The comminution of ores consumes a high portion of energy. Therefore, different pretreatment methods of ores prior to their comminution are considered to reduce this energy. However, the results of pretreatment methods and their technological development are scattered in literature. Hence, this paper aims at collating the different ore pretreatment methods with their applications and results from published articles, conference proceedings, and verified reports. It was found that pretreatment methods include thermal (via oven, microwave, or radiofrequency), chemical additive, electric, magnetic, ultrasonic, and bio-milling. Results showed that the chemical pretreatment method has been used at an industrial scale since 1930, mainly in cement production. The microwave pretreatment results showed positive improvements at pilot scale mining applications in 2017. The results of ore pretreatment using electric and ultrasonic methods showed up to 24% and 66% improvement in energy consumption, respectively. The former and the latter have been piloted for gold and carbonate ore, respectively. Findings also showed that magnetic, radiofrequency, and bio-milling methods have not led to significant reductions in comminution energy. Based on energy reduction, safety, costs, stage of application, and downstream benefits, microwave and electrical pretreatment methods may be focused for applications in the mining industry.

Bu çalışmada, kalsitin dik ve yatay konumlandırılabilen karıştırmalı bilyalı değirmende kuru öğütülmesinde öğütme yardımcısının etkisi incelenmiştir. Değirmenin dik ve yatay konumundan elde edilen sonuçlar tane boyutu (d 50 ve d 90) göz önünde bulundurularak değerlendirilmiştir. Deney sonuçlarından, dik konum için d 50 ve d 90 boyutları öğütme yardımcısız yapılan deneylerle karşılaştırıldığında 2000 g/ton öğütme yardımcısı kullanılmasıyla d 50 boyutunda %40, d 90 boyutunda ise %60 oranında bir iyileştirme sağlanabileceği görülmüştür. Yatay konum için ise; d 50 boyutunda %45, d 90 boyutunda %62 oranında bir iyileştirme yapılabileceği anlaşılmıştır. Ayrıca, öğütme yardımcılı (2000 g/ton) ve öğütme yardımcısı kullanılmadan (0 g/ton) yapılan deneylerden elde edilen ürünlerin taramalı elektron mikroskobu (SEM) görüntüleri çekilerek topaklanma durumları tespit edilmiştir.
