SOURCES: The NATURE

Minerals are naturally occurring inorganic substances with a definite chemical composition and a specific atomic arrangement. They are essential resources used in various industries, from construction and manufacturing to electronics and agriculture. Here are some common sources of minerals:

  1. Ores: Ores are mineral deposits that contain valuable metals or elements in concentrations significant enough to be economically extracted. Examples include iron ore (containing iron), bauxite (containing aluminum), and copper ore (containing copper).

  2. Granite and Marble: Granite and marble are examples of rocks that are rich in minerals. Granite is composed mainly of quartz, feldspar, and mica, while marble primarily consists of calcite or dolomite.

  3. Limestone: Limestone is a sedimentary rock composed mainly of the mineral calcite. It is used extensively in the construction industry as a building material and for making cement.

  4. Sand and Gravel: Sand and gravel are natural deposits of small rock fragments primarily composed of minerals such as quartz and feldspar. They are used in construction and as raw materials for concrete production.

  5. Clays: Clays are fine-grained minerals composed of hydrous aluminum silicates. They are abundant and used in ceramics, pottery, and the production of cement.

  6. Salt: Salt is a mineral composed of sodium chloride and is commonly obtained from salt mines or through the evaporation of seawater.

  7. Phosphate Deposits: Phosphate deposits contain minerals rich in phosphorus, an essential nutrient used in fertilizers and agricultural applications.

  8. Gemstones: Gemstones are minerals or rocks prized for their beauty and rarity. Examples include diamonds, rubies, emeralds, and sapphires.

  9. Sulfur Deposits: Sulfur is a mineral often found near volcanoes or associated with oil and natural gas deposits.

  10. Gypsum: Gypsum is a soft sulfate mineral used in the construction industry for making plaster and drywall.

  11. Coal: Coal is a combustible sedimentary rock containing carbon and various other elements. It is a vital source of energy and used extensively in electricity generation and industrial processes.

PROCESSING

 

Micronized granulates play a crucial role in the production of sintered porcelain, a type of high-performance ceramic material known for its exceptional strength, durability, and resistance to wear and corrosion. In the context of sintered porcelain, the term "micronized granulates" refers to raw materials that have been finely ground into micron-sized particles before being used in the manufacturing process.

The process of utilizing micronized granulates for sintered porcelain typically involves the following steps:

  1. Raw Material Selection: High-quality raw materials, such as kaolin (a type of clay), feldspar, and other minerals, are selected for their purity and specific chemical composition. These materials will serve as the base for the sintered porcelain.

  2. Milling and Micronization: The selected raw materials undergo a milling process to break them down into smaller particles. Micronization involves reducing the particle size to the micron level, typically in the range of a few micrometers to several tens of micrometers. This micronization process ensures uniformity and consistency in the raw material composition.

  3. Blending: The micronized granulates are carefully mixed in precise proportions to create a homogenous mixture that will produce the desired properties in the sintered porcelain.

  4. Shaping: The blended micronized granulates are then shaped into the desired form, such as tiles, slabs, or other products. This can be achieved through various techniques like dry pressing, extrusion, or isostatic pressing.

  5. Compaction: In the compaction stage, the shaped materials are subjected to high pressure to further consolidate the particles and remove any remaining voids.

  6. Sintering: The compacted materials undergo a sintering process, during which they are fired at high temperatures (typically above 1200°C) in a controlled atmosphere. The heat causes the micronized granulates to fuse together, forming a dense and vitrified structure.

  7. Finishing: After sintering, the sintered porcelain products may undergo additional finishing processes, such as glazing or polishing, to achieve the desired surface texture and appearance.

Industries that use quarry granulate include construction, road building, concrete manufacturing, agriculture, and various other manufacturing processes where granular materials are essential components.

It's worth noting that quarrying activities can have significant environmental impacts, such as habitat destruction, soil erosion, and disruption of local ecosystems. As such, responsible quarrying practices, environmental monitoring, and reclamation efforts are crucial to minimize the negative effects on the environment.

Optimizing the uses of micronized granulates in the production of sintered porcelain offers numerous benefits, including improved homogeneity, enhanced mechanical properties, better dimensional control, fire resistance, durability, lesser consumption.  Enhancing the ability to create intricate and detailed designs. The resulting sintered porcelain products are widely used in a variety of applications, including construction, automotive, electronics, aerospace and high-performance industrial components.

Here are a few examples of such unusual micronized mineral applications:

  1. Micronized Zeolites in Odor Control: Zeolites are naturally occurring minerals with unique adsorption properties. Micronized zeolites, due to their increased surface area, are used in odor control applications, such as in pet litter and shoe inserts, to absorb and neutralize unpleasant odors effectively.

  2. Micronized Mica in Cosmetics: Mica is a mineral widely used in the cosmetics industry for its shimmering effect. Micronized mica finds unusual applications in specialized cosmetic products, such as theatrical makeup and special effects, to create dazzling and unique visual effects.

  3. Micronized Calcium Carbonate in Food Additives: Micronized calcium carbonate, with its ultrafine particle size, is used as a food additive in certain applications to act as an anti-caking agent or to enhance the texture and mouthfeel of certain food products.

  4. Micronized Bentonite in Winemaking: Bentonite, a type of clay mineral, is micronized and used in winemaking to clarify wine by removing unwanted proteins and tannins through a process called fining.

  5. Micronized Silicon Dioxide in Antifouling Coatings: Micronized silicon dioxide, also known as silica nanoparticles, is used in antifouling coatings for marine applications. The fine particles help to reduce the adhesion of marine organisms to the hull of ships, preventing biofouling and improving fuel efficiency.

  6. Micronized Talc in Agriculture: Micronized talc, due to its softness and fine particle size, is used in agriculture as a carrier for pesticides and herbicides. The micronized talc particles help improve the dispersion and adherence of active ingredients, enhancing the efficiency of crop protection products.

  7. Micronized Silica in Tire Production: Micronized silica is used in tire production to improve the performance and safety of tires. The addition of fine silica particles to tire compounds enhances traction, reduces rolling resistance, and improves overall tire performance.
