I-Cyanide yaMazwe ngaMazwe (iSodium cyanide) IKhowudi yoLawulo-IMigangatho yoKwamkelwa koMgodi weGolide

Kwishishini lemigodi yegolide, iKhowudi yoLawulo lweCyanide yaMazwe ngaMazwe imisele uthotho lwemigangatho ebalulekileyo yokwamkelwa malunga nolawulo lweCyanide . Le migangatho ibaluleke kakhulu kukhuseleko lokusingqongileyo kunye nokuphila kakuhle kwezilwanyana zasendle.

1. Amanyathelo okuGxininiswa kweCyanide ePhakamileyo kumadama kunye namachibi eentsalela zezimbiwa

Ukuba uxinaniso lwe -cyanide enyibilikayo ye-Weak acid emanzini eedama kunye needama zeTailings ludlula i-50 mg/l, iimigodi zegolide zinyanzelekile ukuba zithathe amanyathelo okuthintela izilwanyana zasendle okanye imfuyo ukuba ingasondeli kumphezulu wamanzi. Amanyathelo anjalo anokubandakanya ukubeka ucingo olujikeleze iidama kunye needama zetailings, ukuzalisa iindawo ezinamanzi ngamatye, okanye ukuzigquma ngeminatha.

2. IiMfuno zeDatha yeCyanide Concentration

Imigodi yegolide kufuneka ibe nedatha eyaneleyo yokubonisa ukuba uxinaniso lwe -cyanide enyibilikayo ene-asidi ebuthathaka kumachibi ayo angasemva, kwiindawo zokukhupha amanzi, kunye namachibi anesisombululo aludluli kwi-50 mg/L. Olu lwazi lubalulekile ekuqinisekiseni ulawulo olufanelekileyo lwe-cyanide - ulwelo olune-cyanide.

3. UThintelo lokubhubha kweZilwanyana zaseNdle

Imigodi yegolide kufuneka ibonise ukuba xa uxinaniso lwe-asidi e-soluble cyanide ebuthathaka emanzini avulekileyo lungekho ngaphezu kwe-50 mg / L, inokuthintela ukufa kwezilwanyana zasendle. Lo ngumba obalulekileyo wokugcina ulungelelwaniso lwendalo kwindawo yemigodi.

4. IMigangatho yokukhutshwa ngokuthe ngqo

Ukuba umgodi wegolide ukhuphela ngokuthe ngqo amanzi amdaka kumanzi angaphezulu, ukuhlangana kwe-asidi ebuthathaka enyibilikayo kwicyanide akufunekanga ibengaphezulu kwe-0.5 mg/L. Ukongeza, iziza zogcino kufuneka zilawulwe ukuthintela ukuvuza, kuqinisekiswe ukuba ukugcwala kwecyanide (i-asidi ebuthathaka decomposable cyanide) kumanzi aphantsi komhlaba kunye nasezantsi kwesiza akugqithi kwimigangatho yobulunga bamanzi aphantsi komhlaba asekuhlaleni.

5. IMimiselo yoMmandla oDibeneyo wokuKhupha uMlambo

Xa ukhupha amanzi amdaka emilanjeni, ngemvume yamagunya alawulayo, indawo edibeneyo yobude obuthile inokusekwa. Nangona kunjalo, i-concentration yamahhala ye-cyanide emanzini ezantsi kommandla odibeneyo kufuneka ingabi ngaphezu kwe-0.022 mg/L. Ngaphezu koko, umgodi wegolide uyafuneka ukuze uchaze inkqubo yawo yokulinganisa.

6. IMigangatho yokukhutshwa ngokungathanga ngqo

Kwimigodi yegolide enemijelo engathanga ngqo, i-cyanide yoxinaniso lwasimahla kumanzi ezantsi kommandla oxubeneyo kufuneka ingabi ngaphezu kwe-0.022 mg/L.

Le migangatho isekwe nguMbutho waMazwe ngaMazwe woLawulo lweCyanide idlala indima ebalulekileyo ekulawuleni ushishino lwemigodi yegolide ulawulo lwecyanide, lujolise ekunciphiseni iimpembelelo ezingalunganga kokusingqongileyo nakwizilwanyana zasendle.
