The mineral raw materials of strontium are mainly sulfide minerals, and the most common industrial mineral is stibnite. The characteristics of the antimony ore are that, regardless of the vein or layer ore, there are large areas of enriched mineral sacs and scattered ore belts. The former contains from about 40% to more than 65%, which is in the form of large blocks with a color similar to gray-blue. China is commonly known as "green sand". The grade of niobium containing bismuth is from a few thousandth to about 20%, and the strontium sulfide is dendritic crystal interspersed in the parent rock, commonly known as “flower sandâ€.
The sand containing less than 10% of strontium should be enriched by beneficiation . The most common type is flotation, which can obtain about 50% of flotation concentrate.
The upper part of the barium sulfide deposit is often completely or partially weathered into oxidized ore, such as vermiculite and strontium ore. When sulphide ore and oxidized ore are symbiotic, they are called sulphide-oxidation mixed bismuth ore The oxidized ore is enriched by bubbling with a boiling furnace or a sintering machine.
Native gold and antimony often symbiotic gold antimony, mercury sulfide and antimony symbiotic thimerosal, and a copper sulfide, lead sulfide or antimony symbiotic hybrid composite, referred jamesonite or tetrahedrite. All of these complex antimony ore have certain industrial significance, especially the brittle bismuth ore mine is currently in the same position in China as the stibnite mine.
Copper, tin-lead concentrate and minor amounts of antimony in antimony host metal smelting process dust enters the byproduct, anode mud is recovered.
The raw materials of the secondary crucible are mainly waste lead battery cement and various hard lead scraps. In industrialized countries, the circulation of secondary cesium often accounts for 30% to 50% of the total consumption of cockroaches.
