ore grade

基本解釋

This paper introduces an improved BP algorithm for estimating ore grade.
本文介紹了一種改進(jìn)的BP算法，用它來進(jìn)行礦石品位估值。
Rutile resource is rich in our country, but rutile ore grade is low and the product is poor competitive because of its high production cost.
我國(guó)天然金紅石資源儲(chǔ)量較大，但絕大部分為低品位的原生礦石，所以加工成本高，產(chǎn)品缺乏市場(chǎng)競(jìng)爭(zhēng)力。
The limitation of geological conditions is important to model a deposit. The geological statistics methods are effective for ore grade estimation and reserve classification.
地質(zhì)控制條件限制是礦床建模的重要手段，地質(zhì)統(tǒng)計(jì)學(xué)方法是礦塊品位估計(jì)以及儲(chǔ)量分級(jí)等的有效方法。

The other factors were better ore grade at Veladero and the fixed sharing mechanism at San Dimas.
