The calculation results indicate that the depressant’s chelating atoms have large coefficient and great activity according to the molecular frontier orbital (HOMO and LUMO) and the orbital coefficients. For S-S type of depressant, S atom in both keto or enol forms won’t affect their HOMO and LUMO patterns and the orbital contributions. For S-O type, the presence of N atom in the ring structure of a molecular will increase the reactivity of O-Cu while weak S-Cu. For O-O type, the electron supply capacity of benzene ring is higher than strain chain, and atom N in strain chain increased their electron supply capacity. The microflotation results basically confirmed the prediction based on the calculation. The simulation results demonstrate that the interaction of a depressant with metals and minerals are affected obviously by the spatial structure and electronic structure of an atom in its molecular.</div> <!-- END MAIN --> </div> <div class="col-12 col-md-4"> <div class="rightBoxes fullWidth"> <div style="padding-bottom:20px"> <a href="https://www.editorialsystem.com/ppmp" target="_blank" class="rightBoxOpt" > <div class="rightBoxOptLine"></div> Submit your paper </a> <a href="https://www.journalssystem.com/ppmp/Guide-for-authors,506.html" class="rightBoxOpt" > <div class="rightBoxOptLine"></div> Guide for authors </a> <a href="https://www.journalssystem.com/ppmp/Archive" class="rightBoxOpt" > <div class="rightBoxOptLine"></div> Archive </a> </div> <div class="rightBox1"> <div class="rightBoxLabel"><div class="boxIcon icon icon-share dirRight"></div>Share</div> <div class="rightBoxContent"> <div class="sharethis-inline-share-buttons"></div></div> <div class="shareSendEmail"><a href="/cdn-cgi/l/email-protection#023d606d667b3f6a767672382d2d7575752c686d77706c636e71717b7176676f2c616d6f2d72726f722d5176707761767770672f6361766b746b767b2f6d642f616a676e63766b6c652f66677270677171636c76712f646d702f616a636e616d727b706b76672f727b706b76672f716772637063766b6d6c2f4644562e333631323a302e322e302c6a766f6e24717760686761763f4b227067616d6f6f676c6622766a6b71227263726770">Send by email</a></div> </div> <div class="rightBox1"> <div class="rightBoxLabel"><div class="boxIcon icon icon-link dirRight" aria-hidden="true"></div>RELATED ARTICLE</div> <div class="otherArticles"> <div class="topPos boxPos"> <a href="https://www.journalssystem.com/ppmp/Pyrite-depression-by-sodium-metabisulfite-and-dextrin-with-xanthates-contact-angle,197068,0,2.html"> Pyrite depression by sodium metabisulfite and dextrin with xanthates: contact angle, floatability, zeta potential and IR spectroscopy studies </a> </div> <div class="topPos boxPos"> <a href="https://www.journalssystem.com/ppmp/Effect-of-activator-on-foam-properties-in-sulfurous-iron-ore-flotation,192825,0,2.html"> Effect of activator on foam properties in sulfurous iron ore flotation </a> </div> <div class="topPos boxPos"> <a href="https://www.journalssystem.com/ppmp/Flotation-separation-influenced-by-the-rheological-properties-of-diaspore-pyrite,174305,0,2.html"> Flotation separation influenced by the rheological properties of diaspore-pyrite mixed pulp </a> </div> <div class="topPos boxPos"> <a href="https://www.journalssystem.com/ppmp/A-nanoparticle-cationic-polystyrene-co-poly-n-butylacrylate-collector-to-eliminate,170899,0,2.html"> A nanoparticle cationic polystyrene-co-poly(n-butylacrylate) collector to eliminate the negative effect of lizardite slimes in pyrite flotation </a> </div> <div class="boxPos"> <a href="https://www.journalssystem.com/ppmp/Investigating-acid-mine-drainage-potential-and-alteration-properties-of-Zn-Pb-wastes,169357,0,2.html"> Investigating acid mine drainage potential and alteration properties of Zn-Pb wastes from Görgü (Malatya, Türkiye) region </a> </div> </div> </div> <div class="rightBox1" > <div class="rightBoxLabel"><div class="boxIcon icon icon-ios-browsers-outline dirRight" aria-hidden="true"></div>Indexes</div> <div style="height: 1px;line-height: 1px;font-size: 0;"> </div> <div class="indexPos boxPos"><a href="https://www.journalssystem.com/ppmp/Keywords">Keywords index</a></div> <div class="indexPos boxPos"><a href="https://www.journalssystem.com/ppmp/Topics">Topics index</a></div> <div class="boxPos"><a href="https://www.journalssystem.com/ppmp/Authors">Authors index</a></div> </div> </div> </div> </div> </div> </div> <div class="row footer1"> <div class="container-fluid stdRow"> <div class="row"> <div class="col-6"> <div class="issn"> <div style="display:inline-block;"> <table cellspacing="0" cellpadding="0" border="0"> <tr><td class="issnLabel">eISSN:</td><td class="issnValue">2084-4735</td></tr> <tr><td class="issnLabel">ISSN:</td><td class="issnValue">1643-1049</td></tr> </table> </div> </div> </div> <div class="col-6 text-right"> <img src="https://www.journalssystem.com/_static/g/c/js_logo_small.png" alt="Journals System - logo"/> </div> </div> </div> </div> <div class="row footer2"> <div class="container-fluid stdRow"> <div class="row"> <div class="col-12"> <div class="copyright"> <div class="text-center">© 2006-2024 Journal hosting platform by <a href="http://www.bentus.com">Bentus</a></div> </div> </div> </div> </div> </div> <div class="hidden"> <a id="cookieAlertLinkId" href="#" data-fancybox="cookie-alert" data-src="#acceptCookiesId"></a> </div> <script data-cfasync="false" src="/cdn-cgi/scripts/5c5dd728/cloudflare-static/email-decode.min.js"></script><script language="JavaScript" type="text/JavaScript"> var acceptCookies = getCookie("acceptOwnCookiesCookie");
