Ancak farkl\u0131 kum t\u00fcrlerinin uygulama alanlar\u0131 farkl\u0131d\u0131r. \u00d6rne\u011fin, baz\u0131lar\u0131 kuvars t\u00fcplerin ve kuvars \u00e7ubuklar\u0131n \u00fcretimi i\u00e7in uygundur, bu nedenle t\u00fcm bu mineraller kuvars potalar\u0131 \u00fcretmek i\u00e7in kullan\u0131lamaz.<\/p>\n
Asl\u0131nda, esas olarak Amerika Birle\u015fik Devletleri, Norve\u00e7 ve Hindistan’da yo\u011funla\u015fan kuvars potalar\u0131 \u00fcretmek i\u00e7in ger\u00e7ekten uygun olan \u00e7ok az yatak vard\u0131r. \u015eu anda d\u00fcnyada y\u00fcksek safl\u0131kta kuvars kumu \u00fcretebilen sadece \u00fc\u00e7 \u015firket var, bunlar Amerika Birle\u015fik Devletleri’nde Unimin, Norve\u00e7’te TQC ve yerli kuvars hisseleri.<\/p>\n

Unimin ve TOC, Amerika Birle\u015fik Devletleri’nde maden kullan\u0131r, ancak kuvars madenleri ili\u015fkili madenler oldu\u011fundan, \u00e7\u0131kt\u0131y\u0131 do\u011fru bir \u015fekilde \u00f6l\u00e7mek zordur. Ayr\u0131ca Unimin gibi \u015firketler son derece entegredir ve kuvars bunun sadece bir par\u00e7as\u0131d\u0131r ve ili\u015fkili bir maden oldu\u011fu i\u00e7in kuvars \u00fcretimini art\u0131rmak i\u00e7in di\u011fer \u00fcr\u00fcnleri de buna g\u00f6re art\u0131rmak gerekir. Bu nedenle, g\u00f6receli geni\u015fleme s\u0131n\u0131rl\u0131d\u0131r. Ayr\u0131ca Unimin, fotovoltaik kum \u00fcretmenin yan\u0131 s\u0131ra yar\u0131 iletken kum da \u00fcretiyor ve yar\u0131 iletken kum daha pahal\u0131, dolay\u0131s\u0131yla \u00fcretim kapasitesini aktaracak g\u00fc\u00e7 yetersiz.<\/p>\n
Amerika Birle\u015fik Devletleri’ndeki Hint madenleri olan madenler d\u0131\u015f\u0131nda, \u00e7ok az yerli kuvars kumu madenleri pota olarak kullan\u0131labildi\u011finden, yerli \u015firketler \u00e7o\u011funlukla Hindistan’dan maden sat\u0131n almakta ve kuvars hisselerinin \u00e7o\u011fu Hint madenlerini kullanmaktad\u0131r. Hindistan madeninden elde edilen kum, bir \u00fcr\u00fcn haline getirildikten sonra \u00e7ok az kabarc\u0131klara sahiptir, safla\u015ft\u0131r\u0131lmas\u0131 kolayd\u0131r ve pota kumu i\u00e7in uygun olan makul bir maliyeti vard\u0131r.<\/p>\n
