Ho tloha sebopehong sa pampiri, e entsoe ka likhoele tse lohiloeng. Likhoele li thekesela hammoho ho etsa masoba a mangata a manyane, kahoo ho kenella ha khase kapa mokelikeli ho nepahetse. Ho feta moo, botenya ba pampiri bo ka ba bo boholo kapa bo nyane, sebopeho se bonolo ho sebetsa, 'me ho phutha le ho itšeha ho bonolo haholo. Ka nako e ts'oanang, mabapi le litšenyehelo tsa tlhahiso, lipalangoang le polokelo, litšenyehelo li batla li le tlase.
Ka mantsoe a bonolo feela,pampiri ea ho hloekisa kofie ka sebelisoa bakeng sa karohano, tlhoekiso, mahloriso, decolorization, ho hlaphoheloa, joalo-joalo Sena se bohlokoa haholo bakeng sa ts'ireletso ea tikoloho, bophelo bo botle ba batho, tlhokomelo ea lisebelisoa, ho boloka lisebelisoa joalo-joalo.
Tse ling tsa lisebelisuoa tse sebelisoang pampiring ea filthara kaofela ke likhoele tsa limela, joalo ka pampiri ea sefa ea tlhahlobo ea lik'hemik'hale; tse ling ke likhoele tsa khalase, likhoele tsa maiketsetso, likhoele tsa aluminium silicate; ba bang ba sebelisa likhoele tsa semela le ho eketsa likhoele tse ling, esita le ho kenyelletsa likhoele tsa tšepe.
