Mu mpera z'ikinyejana cya 19, hari umwarimu w'ishuri ry'abanyamerika witwa Kelly Abbasser. Umugabo we yari umusaya muri mine. Umunsi umwe, umugabo we yagaruye Chalcopyrite. Yashakaga ko asukura umufuka w'amavuta akayikoresha muyindi ntego. Yabonye ko mugihe cyo gukora isuku, ibice bito bya chalcopyrite bishobora kubahiriza isabune ya isabune no kureremba hejuru y'amazi, mugihe ubutaka bwarohamye mu ndobo. Ubwanyuma, iyivumburwa kubwimpanuka niyo inkomoko yubuhanga bushya bwo kurira no gutunganya amabuye y'agaciro.
Imyaka irenga ijana irashize, kandi ikoranabuhanga rya Flotation ryakomeje kunonosorwa kandi ibyifuzo byayo byarushijeho kuba byinshi. Nk'uko imibare ivuga ko 90% by'ubutaka butari feri ku isi butunganizwa muri flotation. Byongeye kandi, flotation nayo ikoreshwa cyane. Ikoreshwa mu gutondekanya ibyuma bidakennye, ibyuma byagaciro, ibyuma bya feri, bidafite ibyuma, amakara n'ibindi bikoresho bya minerval.
Mubikorwa bya none, gusaba no kongeramo amashanyarazi byahindutse cyane cyane, kuko nyuma yo kuvurwa hamwe na flotation reagents, kuburyo amabuye y'agaciro arashobora guhinduka, bityo amabuye y'agaciro arashobora guhinduka, bityo akageraho intego yo gutunganya amabuye y'agaciro.
Amateka yiterambere yamabuye yubukungu
Mbere yo guhanga imirongo ya logique, ibihingwa bya firime byambere byakoreshejwe intoki zongeyeho imiti. Kwishingikiriza ku munara bwite w'abakozi ba flotation, gufungura valve imiti byahinduwe mu maguru kugira ngo uhindure igipimo cy'imiti ya flatation.
Mu myaka ya za 1960, nkikoranabuhanga rikuze, injeniyeri y'amazi y'Abanyamerika indogobe andruos yakoresheje ihame ry'amazi yera kugira ngo ahinge imashini ifata urutonde. Muguhindura amajwi numubare wa slato yisahani, umubare wubuvuzi wongeyeho urashobora guhinduka. gutemba.
Ariko kugenzura gusa imiti ya flication ihuye na royoti iri kure cyane. Nyuma ya za 1970, abamurwanyi-bashyizwe mu bikorwa bya microcontrollers (Umuzunguruko uhuriweho) yimuwe mu nganda za gisirikare kugera ku gukoresha ibisivili. Umusaruro munini wagabanije ikiguzi kuri 1/100 mu bihe byashize, Umunyakanada Jack Johns, umukanishi w'imodoka na elegitoroniki, yakoresheje umwanya wa mbere wo kubaka ibimenyetso byo guhinduranya. Mu nama yo kungurana ibitekerezo, umurima w'Abanyamerika (Fisher) Tekinike ya Terefone ya Valve yize tekinoroji ya Jack Johns yazimye kandi igashyirwa mu murima uyobora ikoranabuhanga;
Muri iki gihe, hamwe na powelisation ya PLC Gahunda ya PLC (uhagarariye sitemens ya Brands), abantu barashobora kubaka byihuse valve yanditseho verisiyo yo kugenzura hamwe nubumenyi buke bwo gufata porogaramu. Sisitemu nkiyi irashobora ubu hariho kandi ubucukuzi bwibintu byinshi mubucukuzi bukoreshwa. Mubisanzwe turayita: solenoid valve imashini ifata imashini (cyangwa imashini ifata imbaraga).
Hagati ya 1980, tekinoroji yo guhinduka yakunze gukoreshwa munganda nyinshi. Gukoresha ihame ryo guhinduka kugirango bigenzure popuc pompegm isafuriya irashobora kugera kuri sisitemu yo kugenzurwa na sisitemu ya mbere (solenoid valve yangiza imashini nimashini zifata ikiyiko). Ibi birashobora gufasha abayobozi banje kugabanya imyanda nubuyobozi ku rugero runini.
Nyuma ya za 1980, metewing pompe yatangiye gushingira ku isoko ry'inganda, cyane cyane mu mirima y'amashanyarazi yo gushushanya no kuvura amazi. Kubera ko igishushanyo mbonera cya metering pompe yagombaga gukemura ikibazo cyo gutanga amazi asanzwe, amashusho ya Metering yakoreshejwe cyane mu nganda mvumbure. , amakosa yayo nayo yarashyizwe ahagaragara. Ibibazo bikomeye ni: 1. Urutonde rwabigenewe rwibisohoka rutemba ni muto. Iyo amafaranga make yashyizweho, ikosa rishobora kuba ryinshi nka 50% cyangwa irenga; 2. Diaphragm nyuma yo guturika, imiti izameneka; 3. Igipimo cyurugendo kibarwa rwose kumibare yumurongo hagati yumurongo wa moteri hamwe nigitabo cyumutwe wa pompe aho kuba igipimo cyatanzwe cyo gutanga. Mugihe cyo gukomeza guhindura igipimo cyuruzi, ikosa risohoka ryiyongera. 4. Guhagarika umuyoboro bizatera umutwe utandukana mu gitutu, kandi imiti yasohotse izanduza ibidukikije. 5. Flotation Reagents ifite umwanda nyinshi bizatera umutwe wa pompe 6. Hariho imirongo myinshi yo kugenzura ibirenge hamwe na pipeline, mugutunga no kwishyiriraho bigoye cyane.
Umuganga wumutaliyani Giovanni Battista Voncege Ingaruka Venttuge ukoresheje ihame rya bernoulli hanyuma wahimbye umuyoboro wa Vecturi. Muri 2013, Wilber yakoresheje ihame rya Venturi mu gutanga Flotation Reagent kandi yahimbye VNC ya CNC (Patent No4010.1) ikoresha kuzenguruka amazi ahoraho nkimbaraga zo kongeramo imiti kugirango wongere imiti. Sisitemu yo gufata igenzurwa numuzunguruko wigihangano. Yiswe kandi imashini ya Sydrodynamic.
