• A cikin tafiyar matakai na iyo, musamman ga wasu ma'adanai masu kyau - ma'adanai masu girma ko laka - abubuwan da ke ciki, tarwatsa ɓangaren ma'adinai yana da mahimmanci. Sodium hexametaphosphate na iya taka muhimmiyar rawa a matsayin mai rarrabawa. Alal misali, a cikin flotation na nickel - pyrite ores hade da serpentine, ƙara daidai adadin sodium hexametaphosphate iya tarwatsa flotation ɓangaren litattafan almara. Wannan shi ne saboda yana rage ɗaukar nauyin serpentine a saman nickel - pyrite, wanda ke da amfani ga farfadowa na flotation na nickel - pyrite.

2.Maganin Watsawa

• Sodium hexametaphosphate na iya rage girman yuwuwar ma'adanai. A sakamakon haka, da electrostatic karfi repulsive karfi tsakanin ma'adinai barbashi ƙara. Tsarinsa na kwayoyin halitta, fili mai linzamin polymer tare da tsawon sarkar akalla raka'a 20 - 100, lokacin da aka tallata shi akan saman ma'adinai, kuma yana iya haɓaka tasirin hanawa tsakanin barbashi. A cikin flotation na wasu m - grained phosphate ores, wannan watsawa sakamako zai iya hana aggregation na phosphate da gangue ma'adanai, inganta rabuwa yadda ya dace.

Ƙimar pH na ɓangaren litattafan almara

2.Tasirin Halayen Sinadarai

• Ƙimar pH na ɓangaren litattafan almara yana shafar halayen sinadarai na sodium hexametaphosphate. A cikin mahallin pH daban-daban, digiri na ionization da nau'in sinadarai na sodium hexametaphosphate na iya canzawa. A cikin yanayin acidic, tasirin hanawa akan wasu ma'adanai na iya raunana. A cikin yanayin alkaline mai yawa, yana iya amsawa tare da wasu abubuwa a cikin ɓangaren litattafan almara, yana shafar aikinsa na yau da kullun. Alal misali, a cikin iyo na wasu jan karfe - gubar - zinc ores, rike da dacewa pH darajar (yawanci a kusa da 8 - 10) zai iya tabbatar da cewa sodium hexametaphosphate yadda ya kamata ya hana gangue ma'adanai da kuma inganta flotation na manufa ma'adanai.

Kammalawa

Sodium hexametaphosphate yana taka muhimmiyar rawa a cikin flotation na ma'adanai, ciki har da a matsayin Mai Rage Tsauri da Mai Rarrabawa. Amfani da shi a cikin nau'ikan flotation na ma'adanai daban-daban, kamar su phosphate ma'adinai da flotation na ma'adinai marasa ƙarfe, ya inganta inganci da ingancin rabuwar ma'adinai sosai. Duk da haka, don cikakken amfani da ƙarfinsa, abubuwa kamar yawan da ake buƙata da pH na ɓangaren litattafan almara suna buƙatar a kula da su sosai. Tare da ci gaba da haɓaka masana'antar haƙar ma'adinai, ƙarin bincike kan amfani da sodium hexametaphosphate a cikin flotation na ma'adinai na iya haifar da ingantattun hanyoyin sarrafa ma'adinai masu ɗorewa.
