Chinangwa chekusanzwisisika kwekuwedzera kwemakemikari ndeyekuita kuti uwedzere kushanda kwemakemikari ari mu slurry uye kuchengetedza iyo yakakwana yekuvhara. Naizvozvo, iyo dosing nzvimbo uye nzira yekugadzirisa inogona kusarudzwa zvine musoro zvichienderana nehunhu hwe ore, chimiro chemumiriri uye maitiro ekuita.
1. Donase Nzvimbo
Iko kusarudzwa kwekutamba nzvimbo kunoenderana nekushandiswa uye solubility yemumiririri. Kazhinji, svikiro adjuster inowedzerwa kumuchina wekukuya, kuitira kuti ubvise zvinokuvadza zve "isingadzivisiki" ioni inoita seanenge ajaira kana inhibitors pahuro. Inhibitors inofanira kuwedzerwa pamberi pemuunganidzi uye anowanzowedzerwa kumuchina wekukuya. Activator inowanzowedzerwa kune yakasanganiswa tangi uye yakasanganiswa neiyo slurry mune tangi kwenguva yakati rebei. Muunganidzi uye anopinza mumiririri anowedzerwa kune iyo kusanganisa tangi uye tangi kana girazi remuchina. Kuti vasimudzire kuparadzaniswa uye kupararira kwevanetswa vechirume (senge cresol dema poda, chena poda, marasha, etc.) kazhinji nguva inowanzowedzerwa kumuchina wekunzwa.
Iyo yakajairika dosing inoteedzana ndeye:
.
.
Uye zvakare, sarudzo yekuita doosing nzvimbo inofanirwawo kufunga nezvechimiro che ore uye mamwe mamiriro chaiwo. Semuenzaniso, mune mamwe madonhwe eSulfide-simbi ore flotation zvidyarwa, Xanthate inowedzerwa kumuchina wekugeda, iyo inovandudza kupatsanurwa kwemhangura. Uye zvakare, imwe chete-color flotation muchina wakaiswa mukukwevera kutenderera kuti udzoreredze iyo dissocated coarse ore zvimedu. Kuti uwedzere nguva yekuita yemuteresi, zvakakodzerawo kuwedzera mumironi kumuchina wekukuya.
2. Dosing nzira
Flotation Reagents inogona kuwedzerwa mune imwe nguva kana mumabheti.
Imwe-yenguva yekuwedzera inoreva kuwedzera imwe mumiririri kune iyo slurry panguva imwe isati yasvika. Nenzira iyi, kusunganidzwa kwemumiriri pane imwe nzvimbo yekushandisa yakakwira, chinhu chesimba chakakura, uye kuwedzera kuri nyore. Kazhinji, kune avo vanonyangadza mumvura, havazopururwi pasi nemuchina. Kune vamiririri (senge svutugadzike, lime, nezvimwe, nezvimwewo hazvigone kuita uye kusashanda mukuputika, nguva imwe-dosing inowanzoshandiswa.
Batch Dosing inoreva kuwedzera imwe kemikari mumabheti akati wandei panguva yekufunga. Kazhinji, 60% kusvika 70% yehuwandu huwandu hunowedzerwa pamberi pehurongwa, uye zvakasara makumi matatu muzana kusvika pamakumi mana muzana inowedzerwa kunzvimbo dzakakodzera mumabhandi akati wandei. Nzira iyi inodhonzwa nemabhatani muBatch inogona kuchengetedza iyo kemikari yekuvharidzira pamwe nehurongwa hwekugadzira uye kubatsira kuvandudza kunaka kweiyo pfungwa yekuisa pfungwa.
Kwemamiriro ezvinhu anotevera, Batch yekuwedzera inofanira kushandiswa:
.
(2) vamiririri vari nyore kuita kana kuora mu slurry. Yakadai se kabhoni dioxide, sarufa dioxide, nezvimwe, kana akawedzerwa pane imwe chete pane imwe pfungwa, maitiro achakundikana nekukurumidza.
(3) mishonga ine dosi inoda kudzora kwakasimba. Semuenzaniso, kana kushushikana kwenharaunda kweSodium Sulfide yakanyanya kukwirira, iyo inosarudza icharasika.
