黑龙江省金矿资源丰富,采金历史悠久,砂金储量高居全国首位,素有“金镶边”之誉称.但就已找到的原生金矿矿量与“金镶边”还很不相称. 砂金矿床的发现和开采,往往成为发现原生金矿床的先导,引导找金工作逐步深入.世界上金矿地质工作的发展历史表明,一些重大金矿的发现和开发,大部分是从砂金矿床开始的.随着 Heilongjiang Province is rich in gold resources and has a long history of gold mining, with the highest amount of placer gold reserves in the country, known as “gold-rimmed.” However, the amount of gold ore that has been found is still not commensurate with “gold-rimmed” gold. The discovery and exploitation of placer gold deposits are often the precursors of the discovery of native gold deposits and the gradual deepening of the gold-finding work. The history of the geological work of gold deposits in the world shows that the discovery and development of some major gold mines are mostly from the placer gold deposits With
