The addition of chemical reagents to the flotation process can cause environmental problems. Therefore, efforts are needed to replace chemical reagents with more environmentally friendly materials. In this research, an attempt was made to replace chemical reagents with a commonly found plant extract, namely aloe vera, as a bioreagent. Bioflotation experiments on a laboratory scale were carried out using a Denver flotation cell with an aloe vera reagent as a frother. This gold mineral bioflotation experiment was carried out on a 150 mesh size fraction. The results of increasing concentrate levels by flotation indicate that the aloe vera reagent as a frother is able to produce biosurfactants which replace chemical reagents as a more environmentally friendly biofrother and biocollector. This can be concluded based on flotation experiment data with bioreagent which has been tested showing an Au content value of 10.09 and a recovery of 96.15%, while flotation using chemical reagents shows an Au content value of 10.50 and a recovery of 95.96%. So the use of aloe vera as an environmentally friendly bioreagent in the flotation process releasing low sulfidation gold is more effective than the use of chemical reagents because it is indicated that there is a biosurfactant content in aloe vera.","PeriodicalId":196240,"journal":{"name":"Journal of Metallurgical Engineering and Processing Technology","volume":"44 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140419235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reagents used are chemicals such as frother and collector, which can potentially contaminate the environment. This research explores the potential use of aloe vera as a separating reagent in environmentally friendly gold ore flotation. The feed used consists of 300 grams of gold ore, and the flotation time is set at 15 minutes. XRD analysis is employed to determine the types of minerals contained in the sample, revealing that the sample consists of 97.64% quartz; Enstatite, syn 1.21%; and Clinochlore-1A 1.16%. Atomic Absorption Spectrophotometry (AAS) is the technique used to determine the metal concentration in a sample. AAS analysis indicates an Au concentration in the feed of 3.94 ppm. The Au concentration in the concentrate with the addition of aloe vera extract is 10.57, and in the tailings, it is 0.92, higher than the concentration in the concentrate without the addition of aloe vera extract, which is 10.11, with 1.89 in the tailings. The %recovery from these concentrations with the addition of aloe vera extract is 84.06%, while without the addition of aloe vera extract, it is 63.78%. This study provides evidence that the use of aloe vera in the gold ore flotation process can be a sustainable and environmentally friendly alternative in the effort to improve the separation of valuable minerals from impurities.","PeriodicalId":196240,"journal":{"name":"Journal of Metallurgical Engineering and Processing Technology","volume":"18 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140419771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coalification begins with the burial of organic material originating from plants. The burial, lasting hundreds of millions of years, results in increasing temperatures and pressures, causing physical and chemical changes to the organic material. Methane gas, the largest component of CBM, is formed. Two processes: biogenic and thermogenic. In the early stages of coalification, biogenic methane gas is produced as a byproduct of the activities of decomposing microorganisms (anaerobic bacteria), similar to what occurs in the decomposition of organic waste. Only about 5 to 20 percent is stored within coal. There are four mechanisms for gas storage in coal: absorption, adsorption, free gas, and gas dissolved in water. Among these four mechanisms, adsorption is the most significant, accounting for 98 percent of the stored CBM in a combined system of micropores (coal matrix) and cleats. Coal Bed Methane resources in Indonesia can be found across South Kalimantan, East Kalimantan, Sumatra, and Java.","PeriodicalId":196240,"journal":{"name":"Journal of Metallurgical Engineering and Processing Technology","volume":"121 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140422521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
