Foringoma igxile ezinhlobonhlobo eziphelele zeizisindo zamasondo ezinamathiselwe. Sigxile ekuqondeni nasekuqineni, sinikeza ukukhetha okubanzi kwezisindo zamasondo ezisebenzisa i-lead, insimbi, kanye ne-zinc ukuze kuhlangatshezwane nezidingo ezahlukahlukene zochwepheshe bezimoto kanye nabathandi bazo.isiqeshana se-lead esisindweni samasondoinikeza ibhalansi nokuqina okumangalisayo, okuqinisekisa ukuhamba okubushelelezi nokuphephile kwezimoto zabo bonke osayizi. Zenziwe ngezinto zokuhola zezinga eliphezulu, lezi zisindo zinikeza ukumelana okuhle kakhulu nokugqwala futhi zenzelwe ukumelana nezimo zomgwaqo ezinzima kakhulu. Kulabo abafuna enye indlela elula kodwa eqinile, izisindo zethu zamasondo ezisikiwe ngensimbi ziyisinqumo esifanele. Zenziwe ngensimbi esezingeni eliphezulu, lezi zisindo zinikeza amandla aphezulu nokuqina ngenkathi zinciphisa isisindo sonke esondweni. Uma ukhetha inketho enobungani nemvelo, yethuisiqeshana se-zinc esisindweni samasondokuyindlela engcono kakhulu. Njengoba zenziwe ngokunemba nangokucophelela, lezi zisindo zinikeza ibhalansi efanele ngaphandle kokusebenzisa i-lead, okwenza kube ukukhetha okuqaphela imvelo ngaphandle kokubeka engcupheni ukusebenza.
