Difference between roasting and smelting?
Roasting is a process of heating an ore in the presence of oxygen to remove volatile impurities and convert the ore into an oxide, while smelting involves heating the ore with reducing agents such as carbon to extract the metal from its ore. Roasting is usually done for sulfide ores, while smelting is done for oxide ores. In roasting, the product is an oxide, whereas in smelting, the product is the pure metal.
What is the difference between roasting and smelting?
Roasting is a process where ore is heated in the presence of oxygen to remove sulfur, arsenic, and other volatile impurities. Smelting is a process that involves melting the ore to extract metal from it, usually using a reducing agent like charcoal or coke. Roasting is more focused on removing impurities, while smelting is about extracting the desired metal.
How many traditional areas of study can chemistry be divided into?
Chemistry can be divided into five traditional areas of study: organic chemistry, inorganic chemistry, analytical chemistry, physical chemistry, and biochemistry. These subdisciplines focus on different aspects of chemistry and allow for a more specialized study of the field.
Give the 5 principal of the brnches in chemistry?
The five main branches of chemistry are organic chemistry, inorganic chemistry, physical chemistry, analytical chemistry, and biochemistry. Each branch focuses on different aspects of matter and the interactions between substances. Organic chemistry studies carbon-based compounds, inorganic chemistry focuses on non-carbon compounds, physical chemistry examines the physical properties and behavior of matter, analytical chemistry involves identifying and quantifying substances, and biochemistry studies chemical processes in living organisms.
What are specialised branches of chemistry?
Specialized branches of chemistry include biochemistry (study of chemical processes in living organisms), analytical chemistry (identification and quantification of substances), physical chemistry (study of how matter behaves on a molecular and atomic level), and environmental chemistry (study of chemical interactions in the environment).

What is a good alternative method for roasting meat without using a roasting rack?
A good alternative method for roasting meat without using a roasting rack is to place the meat on a bed of vegetables or herbs in the roasting pan. This elevates the meat slightly and allows for air circulation, similar to using a roasting rack.
What are the methods of roasting in pyrometallurgy?
In pyrometallurgy, roasting is primarily conducted through three methods: sulfurizing roasting, oxidizing roasting, and chloridizing roasting. Sulfurizing roasting involves adding sulfur to convert metal oxides into sulfides, while oxidizing roasting helps in transforming sulfide ores into oxides by introducing oxygen. Chloridizing roasting utilizes chlorine to convert metal oxides into chlorides, facilitating further extraction processes. Each method is tailored to enhance the recovery of specific metals from their ores.
