Chile's government is considering phasing in a proposed ban on glacial mining to limit projects high in the Andes by some big copper companies. Chile's constitutional assembly has approved a proposal to ban mining in glaciers, protected areas, and areas vital to protecting the country's water system.
Chile's mining minister, Marcela Hernando, said about 20 mines had been identified in protected areas, some close to glaciers, including Codelco's El Teniente and Andina projects and Anglo American Plc's Los Bronces project.
The new measures for glaciers and other protected areas will put about a fifth of Chile's copper Calcium Stearate,Calcium Stearate Overview, Application of calcium stearate,Calcium stearate price,Calcium stearate suppliers prices are predicted to increase in the next few days.
Calcium Stearate Overview
Calcium stearate, molecular formula (C17H35COO)2Ca. White, odorless fine powder, absorbs water in the air. Insoluble in water, slightly soluble in hot ethanol and ether. Reacts with strong acids to generate stearic acid and corresponding calcium salts. Low toxicity.
Application of calcium stearate
Unlike traditional soaps and potassium soaps, calcium stearate is a waxy substance with low solubility in water. It is also easy and inexpensive to produce, and has low toxicity.
Calcium stearate is used as a flow agent and surface modifier in some confections.
This is a waterproof fabric.
Lubricant in pencils and crayons.
The utility model relates to a lubricant for producing a dry drawing method with a wire rod.
The concrete industry uses calcium stearate to control the weathering of cement products used in the production of concrete blocks (ie, pavers and blocks), as well as for waterproofing.
In paper production, calcium stearate is used as a lubricant to provide good gloss and prevent dust and fold cracks in paper and board manufacturing.
In plastics it is used as an acid scavenger or neutralizer (up to 1000 PPM), lubricant and mold release. Can be used in plastic colorant concentrates to improve pigment wetting. In rigid PVC, it accelerates fusion, improves flow and reduces mold swell.
Applications in the personal care and pharmaceutical industries include tablet release agents, anti-blocking agents and gelling agents.
Calcium stearate is an ingredient in some types of antifoams.
Calcium stearate in food is a synthetic ingredient used in food as an anti-caking agent, mold release agent, lubricant, binder, emulsifier and thickener. European Food Additive Number E470a. It can also be used in cosmetics, pharmaceuticals, plastics and other applications.
The main raw material of calcium stearate - stearic acid is a naturally occurring saturated fatty acid in animal fats and vegetable oils in the form of glycerides.
Common animal sources: suet, tallow, and lard.
Common plant sources: cocoa butter, soybean oil, palm oil, coconut oil, olive oil, and corn oil.
Most of the stearic acid used to produce calcium stearate comes from vegetable oil, so it can be called vegetable calcium stearate.
