At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 5500 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The halides are the \"salt minerals\", and have one or more of the following anions: Cl-, F-, I-, Br-.\n\u003C\u002Fp>\u003Cp>Sylvite is similar to halite in chemistry & physical properties, but is less common.  Sylvite is KCl - potassium chloride.  It has a nonmetallic luster and varies from clear to white to other colors due to impurities - often red from hematite.  Sylvite is soft (H=2), water soluble, and has cubic cleavage.  Sylvite rock (sylvitite) flows under intense pressure from burial, as does rock salt (halitite).  Sylvite flows much more readily than does halite.  Some shafts drilled through sylvite have quickly closed shut by sylvite flow.  The quickest way to identify sylvite is by taste.  It has a strong bitter salty taste.  Halite lacks the sharp bitter taste of sylvite.\n\u003C\u002Fp>\u003Cp>Sylvite is an evaporite mineral - it forms by the evaporation of seawater (along with halite, anhydrite, gypsum, and other minerals).  Sylvite has economic significance as the principal source of potassium.  The K is most frequently used as an ingredient in agricultural fertilizers.\n\u003C\u002Fp>\n\u003Cpre>------------------------\n\u003C\u002Fpre>\n\u003Cp>Photo gallery of sylvite:\n\u003C\u002Fp>\nwww.mindat.org\u002Fgallery.php?min=3850","James St. John",1547,1119,{"id":388,"source_url":389,"license_code":390,"credit_html":391,"title":392,"description":393,"author":394,"original_width":395,"original_height":396},81654,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=121246438","Public domain","User:Shinichi, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=121246438\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Silvina - 2007.jpg","Silvina (cloruro de potasio)","User:Shinichi",1200,915,{"id":398,"source_url":399,"license_code":302,"credit_html":400,"title":401,"description":402,"author":403,"original_width":404,"original_height":405},23401,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=356437","Luis Miguel Bugallo Sánchez (Lmbuga Commons)(Lmbuga Galipedia) Publicada por\u002FPublish by: Luis Miguel Bugallo Sánchez, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=356437\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Mineral Silvina GDFL105.jpg","Self made.
