Instances of the adverse effects of naturally occurring carbonaceous
material in mineral processing has been documented
elsewhere. For example, reduction in gold recovery during cyanide
leaching of gold concentrates due to adsorption of dissolved gold
onto carbonaceous material has been observed (Adams and Burger,
1998; Pyke et al., 1999; Allan and Woodcock, 2001). Hence, attempts
were made to depress carbonaceous material using sodium
naphthalene sulphonate during flotation of gold bearing sulphide
minerals, in order to eliminate or reduce its presence in the cyanidation
stage (Pyke et al., 1999). Similarly, a 60/40 mixture of dextrin
and naphthalene disulphonate was used at the copper
concentrator at Mt. Isa, in order to depress iron sulphide gangue
minerals coated with hydrophobic graphitic carbon (Grano et al.,
1991). In both cases, limited improvements were obtained due to
undesirable depression of valuable minerals at higher concentrations
of depressant.

自然发生的碳质的材料的不利影响的事例在矿物处理的被提供了 在别处。 例如，对金子补救的减少在氰化物浸出金集中期间由于被溶化的金子的吸附在碳质的材料上的被观察了(亚当斯和汉堡， 1998年; Pyke等， 1999年; 亚伦和鸟鹬2001)。 因此，使用钠，尝试被做了压下碳质的材料 萘磺酸盐在产金的硫化物的漂浮时 矿物，为了消灭或减少它的在氰化法阶段(等Pyke的存在， 1999)。 同样，糊精60/40混合物 并且萘二磺酸盐使用了在铜 在Mt.
