Calcium carbonate is the major source of cement industry in png. Name other high grade limestone
Other high-grade limestone sources for the cement industry in PNG include:
1. Dolomite: Dolomite is a type of limestone that contains magnesium as well as calcium carbonate. It is sometimes used as a raw material in the cement manufacturing process.
2. Chalk: Chalk is a soft, white limestone composed mainly of calcium carbonate. While it may not be as high-grade as calcium carbonate, it can still be used as a source of limestone for cement production.
3. Marl: Marl is a type of sedimentary rock that contains a mixture of clay minerals and calcium carbonate. It can be used as a raw material in cement manufacturing when blended with other high-grade limestone sources.
4. Oyster shell: In some regions with coastal areas, crushed oyster shells can be used as a calcium carbonate source for cement production. Oyster shells are rich in calcium carbonate and can be a sustainable alternative to traditional limestone sources.
5. Travertine: Travertine is a form of limestone deposited by mineral springs. It is commonly used as a building material but can also be utilized in the cement industry as a high-grade limestone source.
These are just a few examples of other high-grade limestone sources that can be used in the cement industry in PNG, apart from calcium carbonate. The availability of these limestone sources may vary depending on the specific location within the country.
Other high-grade limestone sources apart from calcium carbonate that are commonly used in the cement industry include:
1. Dolomite: Dolomite is a sedimentary rock composed mainly of calcium magnesium carbonate. It contains both calcium carbonate and magnesium carbonate, and is used as a source of both elements in cement production.
2. Chalk: Chalk is a soft, white, porous limestone composed mainly of calcium carbonate. It is commonly used in cement manufacturing due to its high calcium content.
3. Marl: Marl is a fine-grained, loose sedimentary rock composed primarily of clay and calcium carbonate. It is often used as a source of calcium carbonate in cement production.
4. Shelly limestone: Shelly limestone is a type of limestone that contains a significant amount of fossilized shell fragments. It is used in the cement industry as a source of calcium carbonate.
5. Oolitic limestone: Oolitic limestone consists of small spherical grains called ooids, which are composed of concentric layers of calcium carbonate. It is a high-grade limestone used in cement production.
These are some examples of high-grade limestone sources that are used in the cement industry apart from calcium carbonate.
To find other high-grade limestone sources in Papua New Guinea (PNG) apart from calcium carbonate, you can follow these steps:
1. Research Geology Reports: Look for geological reports or studies specific to PNG. These reports often provide information about the types and locations of different high-grade limestone deposits. Websites of government agencies, universities, or geological surveys of PNG can be good places to start your search.
2. Consult Mining experts: Reach out to experts in mining or geology, either through academic institutions or industry associations. They may have extensive knowledge about the limestone resources in PNG and can provide information on alternative high-grade limestone sources.
3. Contact Mining and Cement Companies: Get in touch with mining or cement companies operating in PNG. These companies deal with limestone on a regular basis and may have knowledge about other high-grade limestone deposits apart from calcium carbonate.
4. Engage in Forums/Discussions: Participate in online forums or discussions related to geology, mining, or construction in PNG. Engaging with professionals in these fields can provide you with valuable insights and information on high-grade limestone sources.
By following these steps and conducting thorough research, you should be able to identify alternative high-grade limestone sources in Papua New Guinea, which could be suitable for the cement industry.
