chemical processes. The process for changing metal in to gold is called transmutation. Great energy was dedicated to the quest for the philosopher’s stone, a mythical metal that was said to be necessary to convert cheap metal into gold. The philosopher’s stone was also thought to be capable of creating a chemical concoction called

Flux Stone: Crushed limestone is used in smelting and other metal refining processes. In the heat of smelting, limestone combines with impurities and can be removed from the process as a slag. Portland Cement: Limestone is heated in a kiln with shale, sand, and other materials and ground to a powder that will harden after being mixed with water.

Marble is a metamorphic stone formed when limestone is subjected to intense heat, pressure and chemical solutions, causing the stone to reform into an interlocking structure of calcite, aragonite, and sometimes dolomite crystals. Marble formed from very pure limestone is white, but the presence of other minerals, as well as clay, silt
The mechanism of stone formation include nucleation of stone constituent crystals, their growth or aggregation to a size that can interact with some intrarenal structure, their retention within the kidney or renal collecting system and further aggregation and/or secondary nucleation to form the clinical stone. This sequence is depicted in Figure 1.

Chemical weathering does not break rocks into smaller fragments through wind, water, and ice (that's physical weathering). Nor does it break rocks apart through the action of plants or animals (that's biological weathering). Instead, it changes the chemical composition of the rock, usually through carbonation, hydration, hydrolysis or oxidation.

WEATHERING OF STONE MOUNTAIN GRANITE by WILLAI~D H. GRANT Emory University, Atlanta, Georgia ABSTRACT The weathering of Stone Mountain Granite (adamellitc) forms kaolinite, endcllite, allophane and gibbsite of which kaolinite is the most stable. Bulk density ranges from 2.65
Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier).If the wind is dusty, or water or glacial ice is muddy, erosion is taking place. The brown color indicates that bits of rock and soil are suspended in the fluid (air or water) and being transported from one place to another. This transported material is called sediment.
Spheroidal weathering is a form of chemical weathering that occurs when a rectangular block is weathered from three sides at the corners and from two sides along its edges. It is also called “onion skin” weathering.
Aluminum Anodizing. Type II and Type III anodizing is an electrolytically derived oxide surface coat which arises out of the aluminum.

They have the features: big crushing ratio, even granularity, simple structure, reliable working condition, convenient repair and economical operation.
The term sulfation often connotes a deleterious effect; an example is the accretion on statuary of unsightly films resulting from the action of airborne oxides or sulfur on calcium minerals in the stone. Another undesirable process called sulfation is the accumulation of a crystalline form of lead sulfate on the plates of lead–acid storage ...
