一、概述可选性曲線圆的形式如第一圖所示。第一圖為一正方形圖,在左側的縱座標上畫有自上而下的格子,數值由0至100,代表輕產品(卽尾鑛)的选出率(卽佔原鑛量的百分數)。在右側的縱座標上,畫有自下而上的格子,數值每為由0到100,代表重產品(精鑛)的选出率。下边的横座標畫有由左至右的數值,為由0到100格子,用以表示精鑛品位,尾鑛品位,基本部份的品位及实收率值。上
First, an overview of the optional curve The form of a circle as shown in the first figure. The first graph is a square graph with a top-down grid on the left-hand ordinate, with values from 0 to 100, representing the selection rate of light products (卽 tailings) (百% of ore) . On the right ordinate, a bottom-up grid is drawn with values ranging from 0 to 100, representing the selection rate of heavy products (concentrate). Bottom of the horizontal bar marked with left to right values from 0 to 100 grid, to indicate the concentrate grade, tailings grade, the basic part of the grade and the value of the actual value. on
