DTH drilling refers to a method where the drilling bit is located at the end of a drill string, below the surface of the ground. This technique is distinguished by the use of high-performance percussion hammers, which are positioned on the drill bit. DTH drilling involves the use of compressed air to deliver rapid impacts, breaking rock into smaller fragments. This method is particularly effective in hard rock formations, making it a preferred choice for mining operations and various drilling applications.

  • Starch is a natural carbohydrate sourced from plants, primarily from corn, potatoes, and wheat. When modified, its properties change, allowing it to perform better in various culinary applications. E1450 specifically is created through the acetylation process, where the hydroxyl groups of the starch molecules are replaced with acetyl groups. This modification imparts unique qualities to the starch, making it more stable and effective in certain conditions.


  • Cyanide is a highly toxic chemical compound that has been utilized in the mining industry for over a century to extract gold from ores. This process, known as cyanidation, has been pivotal in making gold mining economically viable by allowing for the efficient extraction of this precious metal even from low-grade ore. Here, we explore the mechanics of cyanide in gold extraction, its implications for the environment, and alternative methods being researched and employed.


  • Carnauba wax, with its impressive range of applications and natural origins, serves as a significant glazing agent across food, cosmetics, and automotive industries. Its ability to enhance appearance, extend shelf life, and provide protective qualities underscores its importance in the market. As the demand for natural and sustainable products continues to grow, carnauba wax stands poised to play an even more prominent role, appealing to consumers who prioritize health, safety, and environmental responsibility in their purchasing decisions.


  • Despite their many benefits, the application of natural food stabilizers does come with challenges. The effectiveness of these stabilizers can be influenced by various factors, including pH, temperature, and the presence of other ingredients. Thus, meticulous formulation and testing are essential to ensure that the desired texture and stability are achieved.
