Izilwandle azicebile kuphela emithonjeni yamanzi, umhlaba wezitshalo nezilwane, kodwa futhi kukhona namaminerali ahlukahlukene. Ezinye zazo zisemanzini futhi ziyoncibilika, ezinye zilele ezansi. Abantu bathuthukisa ubuchwepheshe obuhlukahlukene bokumba, ukucubungula nokusetshenziswa ezindaweni ezahlukahlukene zomnotho.
Izinsalela zensimbi
Okokuqala, iWorld Ocean inezinqolobane ezibalulekile ze-magnesium. Kamuva isetshenziswa kwezokwelapha nensimbi. Njengoba iyinsimbi elula, isetshenziselwa ukwakhiwa kwezindiza nezimoto. Okwesibili, amanzi olwandle aqukethe i-bromine. Njengoba usuyitholile, isetshenziswa embonini yamakhemikhali nakwezokwelapha.
Kunezinhlanganisela ze-potassium ne-calcium emanzini, kepha ziningi ngokwanele emhlabeni, ngakho-ke akukakudingeki ukuzikhipha olwandle. Ngokuzayo kuzombiwa i-uranium negolide, amaminerali angatholakala nasemanzini. Kubekwe izingcezwana zegolide ezitholakala phansi olwandle. I-Platinum ne-titanium ores nayo iyatholakala, efakwa phansi olwandle. I-Zirconium, i-chromium ne-iron, ezisetshenziswa embonini, zibaluleke kakhulu.
Izinsimbi ezifakwa ensimbi cishe azimbiwa ezindaweni ezisogwini. Mhlawumbe izimayini ezithembisa kakhulu zise-Indonesia. Izinqolobane ezinkulu zikathayela zitholakale lapha. Imali edonswa ngokujulile izokwakhiwa ngokuzayo. Ngakho ngezansi ungakhipha i-nickel ne-cobalt, i-manganese ore nethusi, insimbi ne-aluminium alloys. Okwamanje, izinsimbi zimbiwe endaweni esentshonalanga ye-Central America.
Ukwakha amaminerali
Okwamanje, enye yezindawo ezithembisa kakhulu ukukhishwa kwemithombo yemvelo kusuka phansi kolwandle nolwandle ukukhishwa kwamaminerali okwakhiwa. Lezi yisanti namatshe. Kulokhu, kusetshenziswa imishini ekhethekile. Utshoki usetshenziselwa ukwenza ukhonkolo nosimende, nawo ophakanyiswa kusuka olwandle. Amaminerali okwakhiwa akhiwa kakhulu phansi kwezindawo zamanzi angajulile.
Ngakho-ke, emanzini olwandle kukhona imithombo ebalulekile yamaminerali athile. Lokhu ikakhulukazi kuyinsimbi esetshenziswa embonini, kwezokwelapha nakwezinye izimboni. Imboni yezokwakha isebenzisa izinsalela zokwakha eziphakama kusukela ekujuleni kolwandle. Futhi lapha ungathola amatshe ayigugu namaminerali afana nedayimane, i-platinum negolide.
