The average crystalline size was calculated as 1.66, 1.60, 1.45, and 1.47 nm for the ZCM1, ZCM2, ZCM3, and ZCM4 nanosheets, respectively. TEM analysis revealed the presence of crumpled nanosheets. The bandgap of the ZCM1, ZCM2, ZCM3, and ZCM4 nanosheets were 3.99, 3.78, 4.03, and 4.09 eV respectively.

It is essential to understand the effect of voidage on the true ignition and smoldering behavior of wood dust layer on hot plates. In this study, wood dust and shavings were selected as experimental materials. The effects of voidage on the minimum ignition temperature of the dust layer (MITL), ignition delay time, and smoldering behaviors were investigated by means of a hot plate test. The results showed that the addition of large-sized shaving particles significantly enhanced the overall voidage of the dust layer. With the increased deposit voidage, the ignition delay time decreased, and smoldering propagation accelerated. When the shavings content was less than 50%, the MITL decreased; however, further addition of shavings significantly increased the MITL. The analysis shows that voidage affects the ignition and smoldering behavior of the dust layer mainly by influencing oxygen transport and heat transfer processes.

In this work, application of calcium hypochlorite (Ca(ClO)2) and carboxymethyl chitosan (OCMC) as combined depressants for selective flotation separation of chalcopyrite from pyrite was investigated. A maximum recovery difference of 71.35 % between both minerals is observed under the recommended conditions ([Ca(ClO)2] = 60 mg/L, [OCMC] = 400 mg/L and 40 mg/L SBX at pH=8). Besides, the copper-sulfur flotation separation indexes were assessed by the artificial mixed-mineral tests. Results of contact angle measurement, zeta potential and adsorption amount analysis reveal that the combined depressants severely impede the collector adsorption onto pyrite surfaces, and has a light effect on the chalcopyrite. OCMC exhibits a stronger complexing ability on Ca2+ and Fe2+ ions than Cu2+ ions. XPS results confirm that the combined depressant interact with pyrite surfaces intensively, and prompt a deep conversion of S22- and Sn2-/S0 into S2- and SO42- species, as well as a deep transformation of Fe(II)-S into Fe(III)-O/OH on the pyrite surface. ToF-SIMS and thermodynamic calculation results afford the favorable evidence for the selective suppression of the pyrite with added the combined depressant. Thereby the selective oxidation and intense complexation on the pyrite stemming from the combined depressant synergy are responsible for the selective separation of chalcopyrite from pyrite.</div>","PeriodicalId":7232,"journal":{"name":"Advanced Powder Technology","volume":"35 11","pages":"Article 104649"},"PeriodicalIF":4.2,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142171612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
