依馬氏的理論，這種過程呈現出一種倒字型態，其變化由初始增長成熟和衰落個階段組成。當國家或地區經濟發展從農業生產為主向工業制造業為主的生產類型轉變時，其過程就會表現出高礦產資源消費特征，尤其是金屬礦產資源的高消費。
修理后，必須保證原設計要求之各軸承中心間距。按照以上方法對碎石機出現問題的地方進行修理，解決困難，讓設備重新運作，有助于提高生產效率。
（1）細泥質量小，即細泥難于和氣泡相碰撞，即使和氣泡接觸，由于質量則動量也小，難于克服細泥與氣泡間的水化膜，因而細泥很難附著于氣泡。但是，細泥卻很容易粘附在粗粒表面，或稱礦泥覆蓋在粗粒表面，對粗粒浮選起一種“抑制”作用，使粗粒可浮性降低，使浮選過程的選擇性變壞。
