Nugget is ...?

Pane zvinoreva zviviri zvezwi iri. Nhamba yekutanga ndiyo chaiyo. Inoreva nezvemaminerari. Nokudaro, nugget inoreva chikamu chakakosha, zviyo, zvinhu zvinoumbwa mumasikirwo akachena. Hakuchina admixtures yezvimwe zvikamu mairi.

Izwi iri rinobatanidzwa nekuzvisikwa, maitiro ezvisikwa uye kuchena. Zvarinoreva zvakashandurwa kwenguva yakareba, uye zvino zvinogona kushandiswa mupfungwa yekufananidzira mukugadzirisa kwevanhu. Munyaya iyi, nugget munhu ane chipo chepanyama, tarenda kana unyanzvi, asina dzidzo yakakodzera.

Kazhinji inosanganiswa neunyanzvi, kunyange shoko rokuti nugget rinoshandiswa mupfungwa yakazara. Inoreva munhu anogona kukwanisa kuita chimwe chiitiko zvakanaka, pasina kunyatsogadzirira. Izvozvo zvinoreva tarenda, kwete chidimbu chayo chepamusoro.

Dzinopesana muhupenyu hwakanaka, hwakasiyana, hwomuviri wakasiyana. Mu chemistry, nuggets inosanganiswa kuva imwe crystallochemical classification. Zvinoumbwa pasi pezvimwe zvemamiriro emhuka. Zvinowanzowanikwa mu sedimentary rocks.

Zvizhinji zvezvinhu zviri mumasikirwo zviri mumhando yemakemikari kana ores. Munharaunda yehurumende, zvinenge makumi mashanu chete zvinenge zvichiitika, zvizhinji zvadzo zvisingawanzoitiki. Mhepo inonzi Mercury, zinc, chromium, cadmium, tin, indium yakaoma kusangana mumhando yakachena, sekutonga, inoumba muhutano hwemaore. Iron inomuviri wayo wakachena isingawanzoitiki, kazhinji nuggets yayo iripo meteorite. Pakati pezvisiri zvesimbi mumatunhu enyika, sulfuri uye kabhoni zvinogona kuwanikwa.

Muzvisikwa, kabhoni yakachena idhamu uye graphite. Pakati pezvimwe zvikamu zvakawana arsenic, tellurium, antimony. Zvinhu, izvo zvinowanzovapo pasina kusachena, zvinonzi vakanaka kana ineriti. Izvi zvinosanganisira gasi dzakanaka, ndarama, platinum, ruthenium, osmium, palladium, sirivha.

Zvikwata zvakakura

Panguva dzose, nuggets dzaidzingwa kuti dzive vapfumi. Ndiani aisada kuwana daimondi guru kana chidimbu chendarama, iyo yaizogadzirisa pakarepo matambudziko akawanda emari? Muzvakaitika, zvinopfuura gumi nembiri zvakakosha zvikuru zvinyorwa zvinozivikanwa. Zvakawanikwa zvaiwanzopiwa kune mamwe mazita asingazivikanwe kana asingazivikanwi, somuenzaniso, "Anoda," "Cullinan," nezvimwe zvakadaro.
