How Is Sucrose Exacted From Sugar Cane?

The second step of the sucrose extraction process is called affination, in which sugar crystals are liquefied into a type of liquor. Then, the liquor is processed through a stage called carbonation which removes solid byproducts. The liquor is then decolorized to get the white color of granulated sugar and prepared for crystallization. Get price

The Tin Plating Process: A Step

The Benefits of Tin in the Electroplating Process. Why is tin such a popular choice for electroplating? Perhaps the biggest reason is that tin plating — or "tinning" — is an extremely cost-effective process. Because tin is so readily available, it is much less expensive than pricier metals such as gold, platinum Get price

Diamond Mining Methods

Once exposed, the ore in the pit is broken up by blasting. A single blast can break approx. 3,000 tonnes of ore. Once the ore is broken, excavators load the ore into haul trucks and transport it to a primary ore crusher where the diamond extracting process begins. The Kimberley Big Get price

Extraction and Refining of the Platinum Metals

Improved techniques and more modern equipment are always under review, but the basic process for extraction of the platinum metals has remained essentially the same. Rustenburg converter matte contains about 46 per cent of nickel and 28 per cent copper, together with some other base metals and sulphur. The platinum group metals, together with Get price

The true cost of producing an ounce of gold

May 23, 2017The process of finding and mining new sources of gold is a challenging endeavor. Our mining techniques have grown more sophisticated in modern times, but we can still only mine what is available. And the more scarce gold becomes, the more likely we are to see prices increase. Get price

Notes OCCURRENCE AND EXTRACTION OF METALS

The choice of the process depends upon the nature of the ore and the type of the metal. The metal content in the ore can vary depending upon the impurities present and chemical composition of the ore. Some common steps involved in the extraction of metals from their ores are : (i) Crushing and pulverization (ii) Concentration or dressing of the ore Get price

Steps involved in Extraction of metals

Jul 28, 2012In this process, the crushed ore is placed over a conveyer belt, which rotates around two metal wheels, one of which is magnetic. The magnetic particles are attracted to the magnetic wheel and fall separately apart from the non magnetic particles. Due to this separation occurs and process is called magnetic separation. c) Froth floatation Get price

Cement Manufacturing Process
