Ubuchwephesha baseTshayina abasemgangathweni ngabavelisi beNsimbi beCalcium kunye nababoneleli. I-Harvest Enterprise yiCalcium Metal umenzi kunye nomthengisi eChina.Calcium Metal eyona njongo iphambili yentsimbi ye-calcium kukusetyenzwa kumasuntswana esinyithi ekhalsiyam, uze wenze ucingo lwentsimbi ye-calcium okanye ucingo olusulungekileyo lwekhalsiyam, oluthi ekugqibeleni lusetyenziswe ekusulungekisweni kwentsimbi nentsimbi. Indima yayo kukukhupha i-sulfurize kunye ne-deoxidize kunye nokwandisa umbane wensimbi etyhidiweyo kunye nokukhuthaza ukunyuka ngokukhawuleza kokufakwa kwintsimbi etyhidiweyo, esetyenziselwa ukuveliswa kwekhwalithi ephezulu ye-steel.metallic calcium isetyenziswa njenge-agent ekhupha amanzi ekuveliseni utywala obungenamanzi kunye isetyenziswe njenge-desulfurizert kwishishini lepetroleum, esetyenziselwa ukukhupha okanye ukukhupha i-deoxidize kwi-metallurgical industry.Nangona kunjalo, i-calcium compounds inezicelo ezibanzi kakhulu, ngakumbi kwishishini lokwakha.
