Since 200 1, affected by the "bubble phenomenon" of tantalum industry, all the major tantalum enterprises in the world are digesting their stocks, the price of tantalum raw materials has been falling all the way, and the trading volume has shrunk dramatically. In 2006, it has fallen below the lowest level in more than 20 years. Some raw material suppliers without long-term orders and many individual miners have stopped production or reduced production. The demand for other mineral products in the world has risen, and prices have even skyrocketed. However, the price of tantalum raw materials has remained at a low level for several years, further pushing up the global tantalum mining cost and worsening the operating environment. Among them, Guaglia Company, the world's largest supplier of tantalum raw materials, reduced its tantalum ore output by 25% in the fourth quarter of 2006 due to financial difficulties and other reasons; In 2006, Brazilian Metallurgical and Mineral Company (CBMM) and Palana Group Paranapanema also reduced tantalum production and switched to mining more profitable metals. Of course, with the development of the world economy and the development of new uses of tantalum, the demand is further increased, and some potential tantalum deposits are also expected to be explored and developed. After 2007, the international tantalum and niobium market entered a new period of imbalance between supply and demand, in which the raw material price of tantalum ore rose from less than $35/lb at the beginning of the year to $45/lb, and it is still rising. The rising price of tantalum and niobium raw materials causes the shortage of raw materials in processing enterprises, which indirectly leads to the rising price of niobium materials. In addition, in 2007, several major international scientific research projects started one after another, and niobium processing materials have a very important application in them, which further promoted the price increase of niobium materials. However, influenced by the international market, domestic ore prices have returned to the highest level in recent years. If this situation can be maintained for a long time, it will alleviate the embarrassing situation of insufficient raw materials for the sustainable development of tantalum-niobium industry in China to a certain extent, and also make tantalum-niobium mining enter a healthy development stage. However, the rising price of raw materials will have a great impact on domestic low-end product processing enterprises, thus becoming the key to their survival. With the further recovery of the world electronic industry, especially the component industry, the market demand for tantalum-niobium powder, wire and products has shown a huge growth momentum. It is worth noting that due to the increasingly mature technology and competitive advantages in many aspects such as price, capacitor-grade tantalum powder and tantalum wire, a high-end tantalum-niobium export enterprise led by Ningxia orient tantalum industry Co., Ltd., have developed rapidly, and more than 90% of the products have entered the international market and entered the fiercely competitive markets in Europe, America, Japan and South Korea.
