Kuneendlela ezimbili eziphambili zokukhiqiza i-sodium sulfide. Indlela ka-Glauber's salt ifaka hlangana ukuhlanganisa i-sodium sulfate kanye ne-coal powder ngesilinganiso esingu-1:0.5 bese uzifuthumeza esithandweni esivuthako ukuya ku-950°C, ngokuragela phambili nokuvuselela ukukhandela ukuhlangana. Irhasi ye-hydrogen sulfide ekhiqizako kufanele idonswe kusetjenziswa isisombululo se-alkaline, begodu ukubhalelwa ukuhlangabezana namazinga wokuhlanza irhasi ekhutjhwako kungabangela iinhlawulo ezivela eemphathisweni zebhoduluko. Indlela yokukhiqiza isebenzisa uketshezi olulahliweko oluvela ekukhiqizeni itswayi le-barium, okutlhoga amagadango amahlanu wokuhlunga. Nanyana lokhu kwehlisa iindleko ngama-30%, ukuhlanzeka kungafinyelela ku-90% kwaphela.

I-sodium sulfide ikhetha izinto ezisetjenziswako ezisezingeni eliphezulu begodu ilawula ngokuqinileko ukukhiqiza ngokusebenzisa ithekhnoloji ethuthukileko, ngokuhlanzeka okuphezulu nokungcola okuncani, ukuqinisekisa ukutholakala okuzinzileko ngitjho nakuma-oda amakhulu. Tlika lapha ukuthola i-sodium sulfide esezingeni eliphezulu nesebenzako.
