Our Expertise
Mica is a natural mineral. As the formation of its veins and crystals is constrained by complex geological settings, ores from different veins can vary significantly from each other in terms of properties as well as processability. Naturally occurring mica ores often accompanied by many associated minerals and may be mixed with some country rock when they are being recovered.   
    
How to classify and process different types of ores and eventually yield fine product, therefore, requires collaboration of multidisciplinary knowledge and experience in geology, mining, ore dressing and deep processing. As a professional mica producer and supplier, we do not only have a pool of professionals in these fields, but also three decades’ production and trading experience, which form our first advantage.
    
We believe that, like all commodities, for mica products, “cost performance” is the focus of customer concern. Enabling customers to obtain mica filling most suitable for their product needs at a lower cost has always been our expectation. To fulfill this expectation, we have to depend on mature expertise and perfect production conditions, which is our second advantage. It is on these premises that we bring our customers a good variety of product specifications so that they have a wide range of choices.

In addition, we are also able to create more suitable products customized to user demand by relying on our own conveniences.


   Refinement

   Stripping and grinding
     
While the purity of mica powder product appears to be an invisible indicator, it makes great difference to the behavior of the final product.

As the average grade of mica ores recovered from mines is on the order of 50%, high purity from continuous volume production is never independent from mature expertise and perfect production conditions. As many customers of resins and coatings are highly concerned about product purity and expect very rigid free iron control, fine management is even more important. We are proud to say that we have satisfied our customers in all these respects.

On the other side, each refinement will mean a cost increase, which comes in conflict with customer benefit. However, we are never reluctant to give our preference to customer benefit.
The ability of mica to provide strength and rigidity support, increase dimensional and shape stability and some other properties of many products is attributable to its two-dimensional texture. The larger the radius-thickness is, the greater role it plays and, under the same conditions, the less mica is needed.

In practice, the elastic nature intrinsic to mica chips makes them flexure-prone under external forces, thereby causing a loss to these forces. Hence they are more difficult to grind than their brittle counterparts like quartz and carbonate. We are also well experienced in process design and equipment selection that retain the flaky texture of mica, provide for satisfactory stripping during crushing and grinding processes and ensure a larger diameter-thickness ratio of the product.

   Grain size control:

   R&D capability
     
The grain size distribution of mica powder does not only decide the internal and surface behavior of the final product, but also the safety of the customer’s production equipment. Rigid grain size control is an indicator showing the technical level of a manufacturer.

Unlike spherical particles, mica powder displays itself as irregular, light-texture thin sheets. Grading of it is technically challenging for both sieving and pneumatic processes. More importantly, the optimal grain size of mica for customer’s final product is often subject to the technical and equipment limitation of the mica powder manufacturer. In this respect, too, we have good performance to satisfy our customer to the largest extent.
We own a separate laboratory equipped with well-experienced R&D specialists.     
Ever since we started production, we have developed a lot of highly individualized specifications at the request of customers which met their requirements and are highly recognized by them.

We know clearly that, as a production enterprise, the possession of competitive R&D capability does not only reflect its technical and production level, but also its momentum for sustainable development.
