Since the end of January, the price of tungsten has risen steadily and slightly. Yang Chengxiao, chief analyst of Nonferrous Metals of Tianfeng Securities, believes that at present, the number of tungsten concentrate mines in China has been further reduced, and mines in some areas have gradually entered the maintenance phase. In combination with factors such as the strengthening of environmental protection regulations, the upward trend of the tungsten market is basically established. At present, companies are more willing to reluctant to sell, and most of their inventory consumption in the previous period is expected to continue rising. At the same time, the smelting and processing enterprises in the middle and lower reaches are supported by the cost and the prices are rising.
