Kumapeto kwa zaka za zana la 19, kunali mphunzitsi wasukulu waku America dzina lake Kelly Abbasser. Mwamuna wake anali njira yokonza mgodi. Tsiku lina, mwamuna wake anabweza chaccopyrite. Amafuna kuti ayeretse thumba la mafuta ndikugwiritsa ntchito pacholinga china. Anapeza kuti pakutsuka, tinthu tating'onoting'ono ta Chalcophyyr imatha kutsatira sosopo ndikuyandama pamadzi, pomwe nthaka idalowa m'chombo. Pamapeto pake, kupezeka kwangozi kumeneku kunali koyambira ukadaulo watsopano wa flotation ndi njira zamadzi.
Zaka zopitilira zana zapitazo, ndipo ukadaulo wamawuwo udakhala bwino ndipo ntchito zake zafala kwambiri. Malinga ndi ziwerengero, 90% ya ore-osakhala achitsulo padziko lapansi pano amakonzedwa chifukwa cha Flotation. Kuphatikiza apo, mabowo amagwiritsidwanso ntchito kwambiri. Kugwiritsidwa ntchito posankha zitsulo zosowa, zitsulo zamtengo wapatali, zitsulo zamchere, zosakhala zitsulo, malasha ndi zinthu zina zopangira mchere.
Munjira yamakono, kugwiritsa ntchito ndi kuphatikizika kwa ma flotation kumakhala kofunikira kwambiri, chifukwa pambuyo pa chithandizo chamankhwala, chifukwa cha mchere zimatha kusinthidwa, kotero kuti mchere woyatsidwa usasinthidwe ndi thovu, potero kuti akwaniritse Cholinga cha kukonzanso mchere.

Cholinga cha mabwalo olakwika, mbewu zoyambirira zofananira zogwiritsidwa ntchito chowonjezera cha mankhwala. Kudalira zokumana nazo za othamanga, kutsegulidwa kwa valavu ya mankhwala kunali kusinthidwa pamanja kuti asinthe kuchuluka kwa mankhwalawa.
Mu 1960s, monga ukadaulo wamagalimoto okhwima, madzi a ku America amadzimandira, injiniya wa ku American amagwiritsa ntchito ma androos amagwiritsa ntchito mfundo ya madzi opangira scoop-mtundu. Posintha voliyumu ndi kuchuluka kwa scoops pa mbale ya scoop, kuchuluka kwa mankhwala omwe awonjezeredwa. kutuluka.
Koma kungowongolera njira yakumapeto kwa matoma pogwiritsa ntchito kuzungulira sikokwanira. Pambuyo pa zaka za m'ma 1970, ophatikizidwa ndi madera ophatikizika a Microcorsit (dera lophatikizidwa) adasamutsidwira kuchokera pa makampani ankhondo kuti agwiritse ntchito zaboma. Kupanga kwakukulu kumachepetsa mtengo mpaka 1/100 Jack wakale, wamagetsi a Canada, okonda zamagetsi, adagwiritsa ntchito nthawi yake yopuma kuti apange zikwangwani zochokera kuzizindikirira. Pamisonkhano yaukadaulo yosinthira, akhungu aku America (Fisher) akatswiri kampani ya valavu adaphunzira za ukadaulo wa Jack Johns 'akusintha ndikuwongolera mwaluso;
Masiku ano, ndi kutchuka kwa wolamulira wa Plc Pulogalamu (kuyimira Smiemens), anthu amatha kupanga mofulumira solekoid pulve System System System System Proversic Mapulogalamu Othandizira. Dongosolo lotereli likhoza tsopano kulinso migodi yambiri yogwiritsa ntchito. Nthawi zambiri timazitcha kuti: Makina a Solnoid Dosing Makina (kapena makina okoka a mphamvu).
Chapakati pa 1980s, ukadaulo wotembenuka pafupipafupi wagwiritsidwa ntchito mokwanira m'mafakitale ambiri. Kugwiritsa ntchito mfundo yosinthira pafupipafupi kuti muchepetse mapampu opanga ma seaphracm kumatha kuwongolera mopepukidwe kwambiri kuposa makina am'mbuyomu (solenoid valavu dosing makina a dosines ndi supuni ya supuni). Izi zitha kuthandiza oyendetsa zanga kuchepetsa zinyalala ndi kasamalidwe kambiri.
Pambuyo pa 1980s, mapampu othana adayamba kusunthira msika wa mafakitale, makamaka m'minda yofananira ndi mankhwala amadzi. Popeza kapangidwe koyambirira kwa mapampu opimirira inali kuti ithetse vutoli mobwerezabwereza kwa madzi okhazikika, mapampu opitirapo amagwiritsidwa ntchito kwambiri mu malonda amgodi. , zolakwa zake zawululidwanso. Mavuto akulu kwambiri ndi awa: 1. Mitundu yosiyanasiyana yotulutsa molondola ndiyochepa. Mtengo wocheperako wakhazikitsidwa, cholakwika chikhoza kukhala chokwera kwambiri monga 50% kapena kupitilira; 2 .. Mitumbo itadzuka, mankhwalawa ataya; 3. Kuchuluka kwake kumawerengeredwa kwathunthu ubale wapakati pa masewera amoto ndi voliyumu ya pamtamm m'malo mwa kuchuluka kwa zotulukapo. Mukukonzekera kusintha kwamphamvu, kulakwitsa kutuluka kwake kumakula. 4. Kutchinjiriza kwa mapaipi kudzapangitsa mutu wa pamtima kuti uphulike, ndipo mankhwala opukuta adzaipitsa chilengedwe. 5. Kugwedeza kumasuka ndi zosayenera kwambiri kumapangitsa valavu ya pamtanda kuti ikhale yotseka ndi kulephera. 6. Pali madera ambiri ochokera kunja ndi ma pichelines, kukonza ndikukonzanso zovuta.
Katswiri wa sayansi ya ku Italynian Guttista adapeza zotsatira zogwiritsa ntchito mfundo za Bernoulline ndikupanga chubu cha Vernoulir. Mu 2013, Wilber adagwiritsa ntchito mfundo zoperekera ma flotation ndikupanga vlb double system (patent No.101406492626666.1) Kugwiritsa ntchito madzi osokoneza bongo kuti muwonjezere mankhwala. Dongosolo la dosing limayendetsedwa ndi gawo lalikulu la filimu.
