扩大锡生产的任务不仅要基于新的锡石矿床的开发,而且还有赖于新类型锡原料的使用。这些矿石国内不同地区均有发现,但由于它们的物质成分复杂,锡矿物不标准,主要矿物的物理性质研究不够和缺乏对发展锡原料基地有实际成效的处理工艺,所以这类矿石暂时尚未得到利用。 The task of expanding tin production depends not only on the development of new cassiterite deposits, but also on the use of a new type of tin feedstock. These ores have been found in different parts of the country, but such ores have not yet been available due to their complex composition, non-standard tin mineralization, inadequate physical properties of the major minerals, and lack of treatment processes that have proven to be effective in developing tin feedstock bases use.
