where is feldspar found in the philippines


Feldspar is a common mineral found in the Earth’s crust and belongs to the group of rock-forming minerals. It is composed of aluminum silicate minerals with varying amounts of potassium, sodium, and calcium.

Physical Properties: Feldspar exhibits a range of physical properties, including a hardness of 6-6.5 on the Mohs scale, making it moderately hard. It has a glassy or pearly luster and can appear in different colors, including white, pink, brown, gray, and green. Feldspar has a distinct cleavage, and its crystals often form in a prismatic or tabular shape.

Industrial Applications: Feldspar has numerous industrial applications due to its unique properties. It is commonly used in the manufacturing of glass and ceramics, where it acts as a fluxing agent, helping to lower the melting point and improve the overall consistency of the materials. Feldspar is also used in the production of enamels, sanitaryware, tiles, and abrasives.

Gemstone Varieties: Certain types of feldspar are prized as gemstones. For example, the moonstone, a variety of orthoclase feldspar, displays a unique adularescent sheen caused by light scattering from internal structures. Labradorite and sunstone are other feldspar gemstones known for their iridescent play of colors.

Feldspar’s abundance, versatility, and desirable properties make it a valuable mineral in various industries. Its applications range from construction materials to ceramics, glass, and gemstones. With ongoing research and development, new uses for feldspar continue to emerge, expanding its significance in different sectors.

Feldspar In the Philippines

In the Philippines, feldspar is a mineral that is found in different parts of the country, particularly in the Cordillera Administrative Region (CAR) and in the province of Bukidnon in Mindanao. The Philippines has significant deposits of feldspar, which are primarily used in the ceramics and glass industries.

Cordillera Administrative Region (CAR), located in the northern part of Luzon Island, is known for its rich mineral resources, including feldspar. Mines in the CAR extract feldspar from granite rocks, which are abundant in the region. The extracted feldspar is primarily used in the production of ceramics and glass.

Feldspar deposits are also found in the province of Bukidnon in Mindanao. This region is known for its mountainous terrain and rich mineral resources. Feldspar mining activities in Bukidnon contribute to the local economy and provide employment opportunities for the residents.

Feldspar is a crucial component in the ceramics industry. It is used in the production of ceramic tiles, sanitaryware, and tableware. Feldspar helps to lower the melting point of clay-based materials, allowing for better shaping and glazing of ceramic products. The presence of feldspar in the Philippines supports the growth of the ceramics sector, which plays a significant role in the country’s economy.

Feldspar is also an essential ingredient in the glass manufacturing industry. It acts as a fluxing agent, helping to reduce the melting temperature of the glass batch and improve its workability. Feldspar contributes to the transparency, stability, and durability of glass products. The availability of feldspar in the Philippines supports the production of various types of glass, including flat glass, container glass, and specialty glass.

Feldspar Mining Equipment

Feldspar mining equipment refers to machinery and tools used for extracting feldspar from the earth. Feldspar is a widely distributed mineral found primarily in igneous, metamorphic, and sedimentary rocks. It is used in various industries, including ceramics, glass manufacturing, and construction.

Crushers and Grinding Mills: Once feldspar-bearing rocks are extracted from the earth, they are crushed and ground into smaller particles for further processing. Crushers, such as jaw crushers and cone crushers, are used to reduce the size of the rocks. Grinding mills, such as ball mills and vertical roller mills, are employed to further grind the crushed material into a fine powder.

Jaw crushers are primarily used for coarse crushing of feldspar-bearing rocks. They consist of a fixed jaw and a moving jaw that create a V-shaped cavity, where the rocks are gradually compressed and crushed as the moving jaw moves towards the fixed jaw. Jaw crushers are known for their high production capacity and reliability.

Advantages of Jaw crushers:

Jaw crushers have a large feed opening and a steep crushing chamber, which allows for efficient crushing of large-sized feldspar rocks. Jaw crushers can handle various types of feldspar, including hard and abrasive materials. The adjustable discharge setting on jaw crushers allows for precise control over the final product size. Jaw crushers are relatively simple machines, making them easy to operate and maintain. Jaw crushers are generally more cost-effective than cone crushers, making them a popular choice for primary crushing in feldspar processing plants.

Cone crushers are used for secondary and tertiary crushing of feldspar rocks. They have a cone-shaped crushing chamber that rotates around its own axis, allowing the rocks to be crushed between the mantle and the concave liner. Cone crushers are known for their excellent particle shape and high reduction ratios.

Advantages of Cone Crushers:

Cone crushers are ideal for producing finely crushed feldspar particles. The crushing action of cone crushers ensures a uniform particle size distribution, resulting in high-quality feldspar products. Cone crushers can be adjusted to produce different-sized feldspar particles by changing the eccentricity or the CSS (closed side setting) of the machine. Cone crushers are designed to efficiently crush feldspar rocks, providing high productivity and throughput. Many cone crushers are equipped with advanced safety features, such as hydraulic systems that prevent damage from overload or tramp metal.

Magnetic Separators: Magnetic separators are used to separate magnetic minerals, including iron-bearing impurities, from feldspar. This process helps improve the purity and quality of the final product.

Classifiers and Screens: Classifiers and screens are used to separate and classify different particle sizes of feldspar. They ensure that the desired size fractions are obtained for specific applications.

Conveyors and Haulage Equipment: Conveyors and haulage equipment, such as belt conveyors and trucks, are used to transport the mined feldspar from the mining site to processing plants or storage facilities. They facilitate the efficient movement of materials within the mining operation.

It’s important to note that the specific equipment used in feldspar mining can vary depending on the geological characteristics of the deposit, the scale of the operation, and other factors. Safety measures and environmental considerations should also be taken into account to ensure responsible and sustainable mining practices.
