Haeba e le onto e sebelisang oksijene e felletseng, e ka phomotsoa ka nepo, athe haeba e le onto ea moea, ha ea lokela ho phomotsoa, e le ho qoba liphoso tsa phofo e ntle e koalang lerako le ho fofa e bakang liphoso tse tšoeu. Sebaka sa ho qhibiliha ha lehlabathe la silika ke > 1800℃. Haeba ho na le likaroloana tse kholoanyane, boemo ba ho se qhibilihe bo ka etsahala (ho latela bongata ba ho hula le sekhahla sa ho qhibiliha ha onto).
Hona jwale, mehlodi e meholo ya lehlabathe la silica ke: Sebaka sa Fengyang, Profense ya Anhui, Wenchang, Profense ya Hainan, Hepu, Beihai, Zhanjiang, le sebaka sa Heyuan. Kantle ho naha, ho na le lehlabathe la Indonesia, Malaysia, Vietnam le Australia. Fengyang le Heyuan vein quartz ore boleng e le dinako tsa ho qetela tsa kaolin elutriation e entsweng ka lehlohlojane la lehlabathe le silang hape (mohlala, hepu, lehlabathe la zhanjiang), hape ke lehlabathe la lewatle (haholo-holo le na le titanium dioxide e sa tloseng kapa e fokotseng, ontong e na le kgoholeho e itseng, mme masala a titanium dioxide ka khalaseng a ka lebisa ho phetisong ha lesedi la UV khalaseng).
